The "Westport" tornado was the sixth in a series of 9 tornadoes that occurred in Oklahoma during the April 26, 1991 tornado outbreak. This tornado went along a 32-mile path from 1.5 miles west-southwest of Terlton to 1 mile north-northwest of Skiatook. It began at 7:10 pm CST and ended at 8:27 pm CST. The tornado narrowly missed the town of Terlton as it moved east-northeast. Northeast of Terlton and west of State Highway 48, the tornado was weak (F0 damage to trees.) The tornado strengthened as it crossed Highway 48, 0.5 miles south of the Cimarron Turnpike, and produced F1 and F2 intensity damage to structures and power poles. Up to that point it had been one-eighth mile in width.

After crossing Highway 48, the tornado widened rapidly to about 1 mile and intensity increased to F4 strength as it crossed the turnpike. Several cars were swept off the turnpike with five injuries and one fatality. A man was killed when his car was overturned.

65 05/07/1995 1524 34 700 F3 3 6 Cooke TX/ Love/ Carter Near Bulcher TX- 4 SSE Leon- Ardmore- 2 WNW Ardmore

This tornado occurred with an isolated supercell that moved northeastward from Texas across the Red River into southern Love County, and then north- northeastward into Carter County. Air and ground surveys conducted on May 8 (the day after the tornado) revealed a damage path 500 to 700 yards wide and 34 miles long across Love and Carter Counties in Oklahoma, with damage in places consistent with a strong tornado on the high end of the F3 category. Three fatalities and at least 6 injuries are attributed to this tornado.

Following the tornado's path as it moved across Oklahoma, the tornado crossed the Red River into Oklahoma at a point 4 miles south-southeast of Leon (or about 3.5 miles south-southwest of Jimtown) at approximately 3:24 PM CST. The tornado moved northeast and remained near F0/F1 intensity until it reached the Red River RV Ranch on the south side of Highway 96 about 1 mile west of Burneyville. At this RV park, 18 RV's, 12 cabins, 1 store, 1 guard shack, 1 equestrian center, 7 outbuildings, 5 single family homes, and 1 mobile home were destroyed. One other single family home also suffered minor damage. At the entrance to the park, several vehicles, including a delivery van, were rolled off the highway and flipped over. The damage path at this point was 400 to 500 yards wide, and damage was rated as F2.

From there, the tornado crossed Highway 96 to the Falconhead Resort area, where the worst damage was suffered. 20 homes were destroyed and 20 others sustained major or minor damage, including numerous brick homes. At least one of these homes lost all but the northeast exterior wall and a few interior walls in the northeast part of the house. An aircraft hangar and a maintenance building were also destroyed. The damage was rated on the high end of F3 at this point, and the path was measured to be 500 to 600 yards wide.

One half mile north of the Highway 32/Highway 96 intersection, 2 of the 3 fatalities occurred. An 83-year-old female and her 87-year-old sister were killed when their frame home on the west side of the road was picked up and blown 50 feet into a wooded area on the east side of the road. Less than a mile north of this site, the 3rd fatality occurred. A 78-year-old man was killed in his home, while his wife was severely injured. Widespread tree damage was evident along this entire section of the tornado's path, and the intensity along this stretch was rated as F2.

The tornado then decreased to F0/F1 strength and continued north-northeastward across the Love/Carter County Line and toward Ardmore. In Carter County, at least 4 homes, 2 businesses, and 1 public building were destroyed. Four other homes, 5 businesses, and 1 public building received major damage, with minor damage at an additional 5 homes, 6 businesses, and 1 public building.

Specifically, on the southwest side of Ardmore, the tornado strengthened and hit a subdivision of new, well-built homes. The worst damage consisted of 1 or 2 homes that were almost completely unroofed, and had some interior walls down. Damage here was rated at F2. The tornado also hit a high school just north of this subdivision, removing portions of the roof and damaging windows. This damage was rated at the high end of the F1 category.

The tornado then continued northward, paralleling I- 35 on the west edge of Ardmore, and struck a Uniroyal/Michelin tire plant on the west side of the interstate. Significant damage to the sheet metal exterior and roof were noted; however, no structural damage to the steel frame was apparent. In the parking lot immediately to the east of the plant, dozens of automobiles and pickup trucks were damaged or destroyed. Some were tossed, flipped, and stacked on top of one another. At least 1 semi-truck was flipped over on the southwest side of the plant. Based on the damage to the plant and vehicles, the intensity at this point was rated F2.

Immediately north of the tire plant, witnesses reported that the tornado began to go into its dissipation stage. One or two plate glass windows were blown out at a Love's Truck Stop. The canopies over the pump areas and most signs were also destroyed. Damage was rated at F1 here. An electronics warehouse under construction just north of this truck stop had 3 of 4 exterior walls knocked down. At a point about 2 miles north of the Uniroyal/Michelin plant, the tornado took a sharp east-northeast turn and rapidly dissipated at 4:14 PM CST.

Total damage across Love and Carter Counties exceeded $100 million dollars, with $75 million dollars worth of damage in Ardmore alone. Actual damage at the Uniroyal Plant was valued at $45 million, and later production losses due to the damage were estimated at 1.5 million tires.

66 05/03/1999 1726-1848 38 1760 F5 36 583 Grady/ McClain/ Cleveland/ Oklahoma 2 SSW Amber - far N Newcastle - SW Oklahoma City - N Moore-S Del City-W Midwest City

This violent, long-lived tornado was the most infamous of nearly 60 tornadoes that struck central Oklahoma during an unprecedented outbreak on this Monday afternoon and evening of May 3, 1999. The tornado was the 9th of 14 tornadoes produced by a supercell thunderstorm during the tornado outbreak. It formed around 526 pm CST about 2 miles south-southwest of Amber, and grew rapidly to monstrous proportions as it headed NE, paralleling I-44. It moved across Bridge Creek and rural parts of northwest Newcastle, causing continuous F4 and sporadic F5 damage. The tornado was estimated to be a mile in diameter in this area.

It weakened to F2/F3 intensity and narrowed to less than 1/4 mile in width as it crossed I-44 and the South Canadian River northeast of Newcastle and entered far south Oklahoma City SW of 149th and May Ave. around 612 pm CST. But it regained F4/F5 intensity and widened again to 1/2 to occasionally 3/4 mile as it moved northeast across south Oklahoma City, entering Moore just west and north of 12th and Santa Fe.

Still moving northeast and still producing F4 and occasional F5 damage, it crossed I-35 at the Shields Blvd. junction and moved into northeast Moore, at which point it weakened slightly to F3/sporadic F4 intensity and began a gradual turn to the left. This turn took the tornado more to the north-northeast as it crossed I-240 between Bryant Ave. and Sunnylane Rd. It crossed southeastern Oklahoma City and entered Del City as an F4 tornado, width 1/3 to 1/2 mile, along SE 44th between Sunnylane and Sooner Rds, and continued north-northeast to the northwestern part of Tinker Air force Base, near SE 29th and Sooner Rd.

Continuing to turn slowly, it moved almost due north but maintained F4 intensity as it crossed I-40 just east of Sooner Rd. and continued north to between SE 15th and Reno Ave. The tornado then weakened rapidly to F0/F1 intensity as it crossed Reno Ave., and at 648 pm CST dissipated about 3 blocks north of Reno between Sooner Rd. and Air Depot Blvd.

Totals from this tornado include 36 direct fatalities (12 in Bridge Creek, 1 in Newcastle, 9 in southern/southeastern Oklahoma City, 5 in Moore, 6 in Del City, and 3 in Midwest City), 5 indirect fatalities during or shortly after the tornado, 583 direct injuries, numerous indirect injuries (too many to count), 1800 homes destroyed, and 2500 homes damaged. The tornado was also the 100th tornado to strike the Oklahoma City area since 1890. Total damage was estimated at $1 billion.

67 05/03/1999 2005-2020 7 250 F2 1 10 Pottawatomie 2 N Bethel Acres - NW Shawnee (Clarks Heights Addition at I-40/US-177) - 7 E McLoud (Acme Rd/Mocassin Trail)

This tornado formed in rural Pottawatomie County near Independence Road and Drummond Road, or about 6 miles west-northwest of Downtown Shawnee. A few trees were damaged as the tornado moved northeast into the Clarks Heights addition, along US-270, just south of Interstate 40. At 45th Street, a portion of a roof was blown off; a nursery was damaged; awnings were destroyed, and trees were downed. As the tornado crossed US-270, the air conditioner was taken off the roof of the El Charro restaurant. Continuing northeast into the West Gate neighborhood, 15 homes suffered significant damage. Three homes were completely unroofed, warranting an F2 rating, and a number of others were partially unroofed. Other homes suffered shingle damage; a number of large trees were downed, and a garage collapsed. Signs were also downed along the interstate adjacent to this neighborhood.

The next area of significant damage was along the 38800 block of Garrett's Lake Road where a mobile home was destroyed. The frame of the home was blown 50 to 75 yards to the northwest. The disintegration of the mobile home indicated a high F1 or borderline F2 intensity in this area. A few hundred yards to the northeast, the warehouse of Shawnee Light Systems was damaged; one large metal storage building was unroofed, and other buildings were damaged. The tornado crossed Acme Road and struck a number of double-wide mobile homes along Valley View Drive, where one fatality and one serious injury occurred in the same home. The mobile homes most heavily damaged in this area were destroyed, but not disintegrated. To the north, a barn was destroyed, and trees were damaged as the tornado crossed Wolverine Road. The tornado then curved to the north-northwest crossing Acme Road damaging more trees before dissipating.

68 05/03/1999 2010-2038 15 880 F4 1 11 Kingfisher 4 SSW Dover - Dover - 3 NE Dover - 7 ESE Hennessey

This killer tornado was the 6th of seven tornadoes produced by a supercell thunderstorm in northwestern Canadian and Kingfisher counties during the May 3 1999 tornado outbreak. The tornado produced a damage path 15 miles long and ½ mile wide as it tracked through Kingfisher County. The city of Dover took a direct hit. About one-third of Dover's structures were destroyed. The tornado formed 4 miles south-southwest of Dover, and traveled north-northeast crossing route 81 on the north side of Dover, dissipating about 7 miles east-southeast of Hennessey.

F4 damage was observed on the west side of Dover where a steel-reinforced concrete building only had a few walls remaining; large vehicles were rendered apart; mobile homes' frames were wrapped around tree trunks; and trees lost all their branches and most of their bark. One woman was killed inside a large frame home that collapsed. Approximately 34 mobile homes and houses were either damaged or destroyed in Dover. Outside of Dover, damage was rated primarily F1 and was confined to trees, telephone poles, farm quipment, and outbuildings. Total damage was estimated at $2.5 million.

69 05/03/1999 2025-2145 39 1760 F4 2 26 Logan/ Payne/ Noble 3 SW Cimarron City - Cimarron City - Mulhall - 3 ENE Perry

This violent tornado, which killed two people, was the last of 20 tornadoes produced by one cyclic supercell thunderstorm which moved over Caddo, Canadian, Kingfisher, Logan, Payne and Noble counties during the May 3, 1999 tornado outbreak. The tornado formed about 7 miles southwest of Crescent and tracked northeast for 39 miles before dissipating east of Perry in Noble County. A very unusual event took place in Logan County where this tornado, and a second tornado produced by a another supercell thunderstorm about 80 minutes later, affected much of the same area between Crescent and Mulhall in Logan County. Assessment of damage from the individual tornadoes was difficult, and in some areas nearly impossible, due to overlapping damage paths.

Damage from the tornado was first observed about 2 miles west of the intersection of SH33 and SH74 near Twin Lakes Rd., where 2 homes and other businesses were damaged. The width of damage is believed to have increased to nearly 1 mile as it tracked east of Crescent where numerous homes suffered major damage. Damage to 1 brick residence 3 miles east-southeast of Crescent was rated F4. All walls were knocked down, and part of the foundation was removed.

The tornado then tracked through the small community of Abell (6 miles southwest of Mulhall), where 1 woman was killed in her home, and 6 people were injured, and then finally through Mulhall. Approximately 60%-70% of Mulhall's 130 homes were severely damaged or destroyed. In addition, Mulhall's primary water source, a water tower, and the Mulhall/Orlando Elementary School were destroyed.

Lesser damage continued to about ½ mile west of the Logan/Payne County border where tombstones and fences were blown over. Along Interstate 35 in northwest Payne County, a semi-truck trailer was overturned, and 2 cars were flipped. The driver of one of the cars was killed when his vehicle, parked under the Interstate 35 overpass at mile-marker 176.5, was picked up and dropped on its top.

In Noble County, the tornado produced major structural damage in the Boonsboro Addition, a mobile home park located along State Highway 86, 6 miles south of Perry. Approximately 20 mobile homes were destroyed, and dozens of others were damaged. Damage continued northward to a location 3 miles east of Perry, where 3 homes suffered major damage on US 64 and 1 critical injury was reported. In total, approximately 25 homes were destroyed in Noble County, and 50 homes were damaged. Total damage was estimated at $13.1 milloin.

70 06/01/1999 1635-1643 2 350 F3 2 5 Cherokee 6.5 WNW - 6.5 WSW Hulbert

A strong tornado, rated an F3, touched down in far western Cherokee County, possibly as a waterspout on Fort Gibson Lake. The tornado moved south onshore and through the rural Amber Hills housing area, crossing OK Hwy 51, and lifting after tracking through much of the Sequoyah State Park.

In the Amber Hills and Hammer Hill Road areas, a total of 68 homes sustained some form of damage. Of that, 17 single family dwellings and 13 mobile homes were destroyed. Eight single family dwellings sustained major damage and 11 others had minor damage. One mobile home sustained minor damage. Fourteen other single family dwellings and four other mobile homes were affected. In one of the destroyed mobile homes, an elderly man and woman were taking refuge inside. The woman was killed immediately, and the man was seriously injured, dying one week later in a hospital of tornado-related complications.

Across OK Highway 51 in Sequoyah State Park, between 400 and 500 trees were lost to the tornado. The carport at the park manager's residence was destroyed, and an RV was turned on its side. Fortunately, most Memorial Day campers had cleared out, therefore there were no injuries in the park.

71 04/11/2001 0425-0440 13 200 F2 1 1 Coal/ Atoka 3 SE Coalgate - 1 NW Wardville

This tornado formed 4 miles southeast of Coalgate at 4:25 AM CST and tracked northeastward for 8 miles before crossing into northwest Atoka County at 4:34 AM CST. The tornado then continued for another 5 miles before dissipating at 4:40 AM CST. In Coal County, 1 fatalilty and injuries to another person occurred when a mobile home was thrown approximately 200 yards and disintegrated, 4 miles east of Coalgate. In addition, a well-constructed frame home suffered severe roof damage and exterior wall damage in extreme eastern Coal County. In Atoka County, minor roof damage was sustained to a mobile home, and numerous trees were damaged before the tornado lifted.

72 03/28/2007 1816-1854 22 150 EF2 2 0 Lipscomb TX/ Beaver 5 E Booker TX - 7 E Elmwood

The tornado originated five miles east of Booker, TX or between Booker and Darrouzett...about six miles south of the Beaver County and Lipscomb County line at 6:16 PM CST. The tornado remained over open country and no damage or injuries were reported in Lipscomb County. The tornado moved northward and entered Beaver County, Oklahoma at 6:28 PM CST. Damage occurred on a farmstead about one mile into Beaver County severely damaging several outbuildings and a grain bin. Little or no damage occurred to the home.

The tornado continued north and briefly became a large multi vortex tornado before it consolidated into one large funnel. The tornado snapped numerous power poles and large trees. The tornado then struck and destroyed a single family home at 6:50 PM CST where two fatalities occurred. It appeared that the couple killed in the tornado did seek refuge in their small bathroom, which was destroyed. In addition to the small home, a storage barn was destroyed and two vehicles were moved as much as twenty yards. A horse trailer was destoyed as it bounced and rolled for approximately fifty yards. The tornado continued moving north for approximately another six or seven miles, damaging only power poles, fences, and trees before it lifted at 6:54 PM CST seven miles east of Elmwood, OK.

Craig/ Ottawa/ Newton MO/ Barry MO 9.2 NNW Welch - Picher - Quapaw - 3 NE Peoria - Granby MO - Newtonia MO - 3.9 NNE Fairview MO - Purdy MO - 0.2 WSW McDowell MO

This tornado developed at 420 pm CST in northeastern Craig County and continued into Ottawa County. The tornado moved rapidly eastward toward the town of Picher, OK where it destroyed about 200 homes, killed six people, and injured another 150 people at about 540 pm. Damage in and around Picher was rated EF-4 on the Enhanced Fujita Scale. The tornado began moving more southeasterly near Picher and struck the north side of Quapaw, OK. While this tornado was beginning to weaken east of Quapaw, the supercell produced another tornado a few miles east-northeast of Quapaw that merged with this tornado just east of U.S. Interstate Highway 44. After the merger of the two tornadoes, a single tornadic circulation reintensified and became about a mile wide for several miles before moving into Newton County, MO.

The EF-4 tornado crossed into Missouri just north of Iris Road, and tracked east southeast all the way across Newton County to just north of Fairview, MO. Several people were killed in automobiles, including a firefighter who was storm spotting, as the tornado briefly reached EF-4 intensity near the intersection of MO State Highway 43 and Iris Road. One vehicle at this location was thrown 5/8s of a mile. The tornado then extended to a mile wide and EF-3 intensity as it tracked across the intersection of Highway 86 and BB. Many of the 14 fatalities and 200 injuries occurred from just west of MO State Highway 43 to MO State Highway 86. The communities of Granby, MO and Newtonia, MO were also directly impacted from this tornado. The tornado tornado weakened to EF-2 intensity as it tracked across much of Barry County, but it remained deadly as it directly impacted the community of Purdy, MO. One man was killed as he was taking shelter in a mobile home. Numerous structures, trees, and power poles were destroyed. Damage was estimated at $15.6 miiloin in Oklahoma and $60.6 million in Missouri. This was the first EF-4 tornado to occur in Oklahoma since the Enhanced Fujita Scale was adopted by the National Weather Service in 2007.

74 02/10/2009 1848-1943 37 880 EF4 8 46 Montague TX/ Jefferson/ Love/ Carter Near Spanish Fort TX - 1 W Petersburg - Lone Grove - 4 SSE Springer

This long track tornado developed over extreme northern Montague County in north Texas, near the Red River, and continued northeast into Jefferson and Love Counties crossing through rural farmland north of Courtney, Rubottom and Oswalt. The tornado then crossed into Carter County, with sporadic damage noted in the sparsely populated areas in the southwest part of the county. The tornado appeared to reach its maximum width and intensity as it approached and moved through Lone Grove. The tornado destroyed or severely damaged numerous mobile homes, homes and businesses in and around Lone Grove. Numerous mobile homes were completely obliterated with few recognizable pieces left. EF-4 damage was noted at two locations, one in Lone Grove and the other in the Majestic Hills area north of Ardmore. Numerous vehicles were rolled or thrown, some for considerable distances. Six of the fatalities occurred in mobile homes and one in a well-built home that sustained EF-4 damage. The eighth fatality occurred when a truck driving south on U.S. Interstate Highway 35 was hit by the tornado killing the driver.

The tornado continued northeast, with major damage reported in the Majestic Hills addition and crossing I-35 about a mile and a half north of the Prairie Valley Road exit. At least eight homes and a small private school were destroyed in the Majestic Hills neighborhood. It moved through rural areas of Northeast Carter County to the east of Springer. Approximately 46 people were injured, with 14 seriously injured. Eight people died in the Lone Grove area. At least 114 homes were damaged or destroyed, with at least 3500 losing power in and around Carter county. Debris from this tornado was picked up as far away as Sulphur. Monetary damage estimates were not available. Damage was estimated at $3 million.

75 05/10/2010 1620-1651 24 2000 EF4 2 49 Cleveland/ Oklahoma Far north Norman (near Santa Fe/Indian Hill Road) - south Moore - Lake Draper - I-40/Choctaw - 1.5 SSE Harrah

This long-tracked and devastating tornado developed west of U.S. Intertstate Highway 35, northwest of Max Westheimer Airport. Widespread tree, power line/pole damage was reported from near I-35 to the east side of Stanley Draper Lake. Several homes also sustained damage, mainly with mostly roofs receiving significant damage, and some siding was ripped off. Several fences were also knocked down as the tornado moved northeast.

From the east side of Lake Stanley Draper, near Hiwassee Road and SE 89th Street, to just south of Harrah, the damage path became more severe and focused. The tree damage became more severe, breaking at various heights of the tree or being uprooted. Walls of homes collapsed, and debris from the homes scattered in all directions. Several 2x4's punctured roofs and ceilings over numerous structures. A few mobile homes in this area were also completely destroyed.

Where the tornado crossed U.S. Interstate Highway 40, a gas station and drive-in restaurant sustained up to EF-3 damage. The most severe damage, one of the two EF-4 tornadoes of the day, occurred in the Deerfield West Subdivision. A well-built residence here was completely destroyed, with most exterior and interior walls collapsing. The tornado finally lifted 2 miles south of Harrah. In addition to the incredible damage, one person lost their life while trying to flee the tornado.

76 05/10/2010 1632-1659 22 880 EF4 1 32 Cleveland/ Pottawatomie South Norman (0.5 E National Weather Center) - Lake Thunderbird - Little Axe - 4 E Pink

This violent tornado touched down a few hundred yards south of the National Weather Center in Norman, Oklahoma. The damage intensity increased gradually along the path with significant damage beginning as the tornado approached Lake Thunderbird. This tornado crossed Lake Thunderbird, severely damaging two campgrounds and the marina where about 300 boats were docked.

The most severe damage occurred from the Little Axe School to the Cleveland/Pottawatomie county line. Trees were stripped of some bark and branches. Large objects were thrown considerable distances, including some concrete pillars. The metal bleachers near the school were tossed or rolled several hundred yards. Some appliances were also lofted as a dryer was found about 50 feet up in a tree. Considerable structural damage also occurred, as some foundation homes were mostly destroyed. In addition to the damage, one person lost their life as a result of the tornado.

77 04/14/2011 1820-1850 17 1320 EF3 2 40 Atoka 3 E Boggy Depot (5 WSW Tushka) - Tushka - 3 SE Atoka - curving to ~2 E Stringtown

A large tornado began 5 miles west-southwest of Tushka and moved east-northeast through Tushka and about 3 miles southeast of Atoka before curving to the north-northeast and dissipating around 2 miles east of Stringtown. Almost 150 homes and business' were significantly damaged or destroyed, many numerous others sustaining minor damage. Two fatalities occurred in a mobile home to the west of Tushka.

78 05/24/2011 1420-1444 13 880 EF3 1 2 Dewey/ Blaine/ Major 3 W Canton - Canton Lake - 6 WSW Fairview

This large tornado began west of Canton in Dewey County and moved north-northeast toward (and eventually over) Canton Lake. The damage was confined to trees and power poles/lines during the early stages of the tornado. However, more significant damage occurred as the tornado moved into Blaine County.

The tornado moved northeast toward Canton Lake, which is where more significant damage occurred. Near the lake, on both sides where the tornado crossed, significant tree damage occurred. Numerous trailer homes were knocked over or destroyed. On the south side of the lake, two injuries occurred at the Canadian Campground. Several other campers took shelter in a concrete bathhouse. Although the bathhouse sustained damage, no injuries were reported. Other concrete structures (benches, pick-nick tables, etc.) were knocked over or shattered. On the other side of the lake, southwest of Longdale, significant damage continued to more structures and trees.

The large, violent tornado continued due north into Major county. The tornado hit homesteads and barns, severely damaging most structures, and splintering trees and power poles. One of the farmsteads received on the upper end of EF-3 damage, with the house completely collapsing and the trees on the property debarked and snapped. The tornado continued near Cedar Springs, damaging the church roof, and severely damaging a mobile home and several buildings at a farmstead. The tornado finally lifted southwest of Fairview.

79 05/24/2011 1450-1635 63 1760 EF5 9 181 Canadian/ Kingfisher/ Logan 4 ESE Hinton (14 SW Calumet) - near Calumet - El Reno - Piedmont - Cashion - 4 NE Guthrie

This tornado began very close to the Caddo/Canadian County border and quickly became a strong/violent tornado. The tornado destroyed numerous trees, many of which were debarked, before crossing U.S. Interstate Highway 40. Three people died in vehicles near the I-40 Calumet exit, and two other fatalities occurred just northeast of that location. Cars were thrown thousands of feet off the roadways. It is believed that the tornado reached its maximum intensity just after crossing I-40, and it was here that a mobile radar measured winds of greater than 210 mph just off the surface.

The tornado side-swiped the El Reno Oklahoma Mesonet station (located 5 miles west of El Reno) along its path, and the site measured wind gusts of 131 and 151 mph. From this location, the tornado continued northeast, narrowly missing the town of Piedmont. Widespread EF-3, occasional EF-4 damage occurred between El Reno and Piedmont. More widespread EF-4 damage was seen west and north of Piedmont. Especially hard hit was the Falcon Lake neighborhood, near the Kingfisher County border. Two children were killed at this location.

The tornado entered far southeast Kingfisher County before moving into Logan County. However, EF-3 damage occurred just over the Kingfisher County border, debarking trees and significantly damaging buildings. As the tornado continued northeast, the damage was mainly considered EF-2, with damage to mostly outbuildings and trees. The tornado then continued into Logan County.

The tornado moved into Logan County and resulted in two additional fatalities (both of whom were outside when the tornado struck) near Cashion. The tornado destroyed several manufactured homes (both double and single-wide) after entering Logan County. Large high-transmission line tresses collapsed. Trees were debarked with only stumps remaining. Several buildings had most of their exterior walls collapse, with only the inner walls remaining. EF-2 to occasionally EF-3 damage occurred as the tornado neared Guthrie. Luckily, most of the town of Guthrie was spared to the tornado as it moved west and then north of the center of the city. Finally, the tornado dissipated northeast of Guthrie with some minor tree damage. The tornado’s path total path length was 63 miles, and it was on the ground for nearly one hour and 45 minutes. This was the first EF-5 tornado to occur in Oklahoma since the Enhanced Fujita Scale was adopted by the National Weather Service in 2007.

80 05/24/2011 1606-1701 33 880 EF4 1 48 Grady/ McClain/ Cleveland 2 S Chickasha - SW Oklahoma City (near SW 149th and Portland)

This tornado formed on the south side of Chickasha in Grady County, quickly doing EF-2 damage. Mobile homes were damaged and destroyed, trees were uprooted or destroyed, outbuildings were destroyed, and many buildings lost significant portions of their roofs. One fatality occurred as a mobile home was destroyed in the south portion of Chickasha. As the tornado moved northeast of Chickasha, it gained significant strength, with several areas receiving EF-4 damage. Well-built homes were destroyed. Trees were debarked with only stumps remaining. Cars were thrown hundreds of feet. Almost continuous EF-3/occasional EF-4 damage occurred northeast until it crossed into McClain County, 1.5 miles south of Highway 9. The tornado was probably at its strongest as it neared/crossed the Grady/McClain County line. Wind speeds there were estimated near 200 mph in this area.

Significant damage continued as the violent tornado moved over the McClain County border. This may have been the strongest portion of this tornado, with wind speeds near 200 mph. Well-built homes were destroyed, with some cleaned off of their foundation. A concrete dome home was severely damage, mainly by the flying debris. Trees were debarked or destroyed. Very little was left standing for the first few miles into McClain County. Fairly consistent EF-3, with brief periods of EF-4 damage occurred as the tornado approached and then crossed OK State Highway 9, near the OK State Highway 76 junction. The tornado began to weaken as it moved toward the Cleveland County border, with mainly trees and power poles/lines snapped.

The tornado continued into Cleveland County and where some minor tree/power pole/power line damage occurred. A few barns and outbuilding also sustained minor damage east of U.S. Intertstate Highway 44. The tornado dissipated just north of the South Canadian River. The tornado traveled along a path length of 32 miles through three counties in just under an hour, Peak wind speeds were estimated just under 200 mph.

81 08/10/2011 0232-0239 5 400 EF2 1 2 Mayes/ Cherokee/ Mayes 4.5 SSE - 5.5 ESE Locust Grove

The tornado developed on the leading edge of a short convective line of thunderstorms that wasn't undercut by cold outflow. It moved northeast uprooting and snapping a number of large trees within this segment in Mayes County and then moved into the extreme northwestern corner of Cherokee County producing similar damage. The tornado then continued northeastward back into Mayes County.

As the tornado crossed back into Mayes County, it destroyed a double wide mobile home and damaged a single wide mobile home just north of the E590 Road. A woman was killed in the double wide mobile home and two people were injured in the other mobile home. Trees were uprooted and snapped and debris from the double wide mobile home was transported several hundred yards downstream. The tornado damaged another mobile home south of the E580 Road where it destroyed a greenhouse. Numerous trees were uprooted and snapped along the path until the tornado dissipated just south of the E570 Road.

August is one of the least active months for tornadoes in this part of the country so the intensity of this tornado was even more unusual. In fact, this is only the 4th strong tornado (EF-2 or EF-3) that has been confirmed in eastern Oklahoma since 1950.

82 04/14/2012 2242-2326 34 400 EF3 6 29 Ellis/ Woodward 2 SSW Arnett - Woodward - 4 N Woodward

The tornado developed approximately just south of Arnett (Ellis County) at 10:42 PM CST (11:42 pm CDT) on April 14, 2012 and moved northeast. Two homes were categorized as destroyed and a few other homes sustained damage. Trees and power lines were also damaged as the tornado moved toward the Woodward county border. The tornado eventually crossed the border, producing only minor damage (mainly downed trees and power poles/lines) as it moved over mainly rural portions of Woodward County, southwest of the city of Woodward.

At approximately 11:12 PM CST (12:12 am CDT on April 15, 2012), the tornado struck two mobile homes 5 miles southwest of Woodward. The damage here was determined to be EF-2 in intensity, and also resulted in 3 fatalities. The heaviest damage, rated EF-3, was reported as the tornado entered the southwest sides of Woodward around 11:18 PM CST. Several homes and businesses were heavily damaged as the tornado continued northeast. Several more mobile homes were destroyed by the tornado on the north side of Woodward, and resulted in 3 additional fatalities. The tornado finally exited the city of Woodward at approximately 11:23 PM CST, eventually dissipating approximately 4 miles north of Woodward at 11:27 PM CST.

83 05/19/2013 1700-1750 23 1500 EF4 2 10 Cleveland/ Pottawatomie East Norman (8 E downtown) - 6.5 ESE McLoud

A long track tornado began at 5:00 PM CST (6:00 PM CDT) in Cleveland County in east Norman to the north of Lake Thunderbird along 96th Avenue to the south of Tecumseh Road. The tornado moved northeast, crossing the eastern arm of Lake Thunderbird. A number of homes were significantly damaged as the tornado moved east-northeast through neighborhoods from near Indian Hills Road and 168th Avenue SE to the Pottawatomie County line.

The large tornado moved east-northeast into Pottawatomie County at 5:20 PM CST then curving northeast as it approached State Highway 102. The tornado moved through a mobile home park north of Independence Road after crossing State Highway 102. Just northeast of the mobile home park, a permanent home was destroyed with much of the debris blown well to the northeast. It continued northeast crossing U.S. Interstate Highway 40 near the intersection of U.S. Highway 177, then curved north-northeast finally dissipating near Wolverine Road and Coker Road at 5:50 PM CST. One fatality occurred in the mobile home park, and another man was killed in his vehicle.

84 05/20/2013 1356-1435 14 1900 EF5 24 212 McClain/ Cleveland Newcastle (3 NW US-277/SH-130) - 3 WNW Stanley Draper Lake Dam

The violent Newcastle-Moore tornado was first observed at 1:56 PM CST (2:56 PM CDT) developing about one-half mile south of Oklahoma State Highway 37 in northwest Newcastle to the east of Rockwell Avenue. EF4 damage was observed soon after the tornado crossed State Highway 37. The tornado continued to expand in size as it approached the Canadian River and moved into Cleveland County.

The tornado then moved into Cleveland County at 2:04 PM CST from McClain County as it moved northeast across the Canadian River near U.S. Interstate Highway 44. The tornado then turned more east and then east-northeast after crossing I-44. Violent E-F4 damage was again observed as it began to move into progressively higher density residental areas approaching May Avenue.

The center of the large tornado path passed near SW 149th Street and Western Avenue. After crossing Western Avenue, numerous buildings were destroyed and horses killed at Orr Family Farm. Two storage tanks estimated to weigh approximately 10 tons were lifted from Orr Family Farm and landed about one-half mile east.

Moving east, the tornado destroyed much of Briarwood Elementary School, where the NWS storm survey team rated damage as EF-5. Despite the destruction of this elementary school during school hours, no fatalities occurred at the school. As the tornado continued to move east and east-northeast, it moved through much more densely populated suburban neighborhoods of southwest Oklahoma City and Moore where violent destruction was widespread.

The width of EF-4 and greater damage was up to 250 yards wide as the tornado moved through neighborhoods east of Western Avenue. The first two fatalities occurred in a house in the neighborhood just east of Briarwood Elementary, with another fatality in a house as the tornado approached Santa Fe Avenue.

After crossing Santa Fe Avenue, the tornado moved through more suburban neighborhoods and toward Plaza Towers Elementary School. Damage to the school was extensive and seven children were killed when a wall collapsed at the school. Nine other people were killed in eight different neighborhood homes within one-quarter mile of Plaza Towers Elementary, most occurring just south of the school.

The tornado turned northeast as it approached Telephone Road, made a loop near the intersection of Telephone Road and 4th Street, then moved southeast crossing the interstate. Three people were killed when a convenience store along Telephone Road was destroyed. Crossing Telephone Road, the tornado inflicted significant damage to the Moore Medical Center, a post office and numerous businesses along Telephone Road and U.S. Interstate Highway 35.

Although the tornado was more narrow after crossing I-35, it continued to produce EF-4 damage in neighborhoods east of the interstate as it curved east and then again east-northeast. One fatality occurred at a business just east of the interstate, and one final fatality occurred in a home between Eastern Avenue and Bryant Avenue. Consistent EF-4 damage continued until the tornado passed SE 4th Street just east of Bryant Avenue.

Moving east from Bryant Avenue, the tornado continued to produce EF-2 damage with isolated EF-4 damage noted. The density of housing also decreased east of Bryant as the tornado moved east and east-northeast before dissipating at 2:35 PM CST east of Air Depot Blvd. between SE 119th Street and SE 134th Street in southeast Oklahoma City. Overall, over 300 homes experienced EF-4/EF-5 damage along the tornado path.

85 05/31/2013 1703-1744 16 4576 EF3 8 26 Canadian 8 S Calumet - 5.5 S El Reno - 6 SSW Richland

On May 31, 2013, an intense, long-track tornado formed southwest of El Reno. This exceptionally wide tornado took a complex path, rapidly changing in both speed and direction. The tornado spared El Reno and its airport from a direct hit, tracking just south of those locations. The tornado damaged numerous homes along with a few businesses near El Reno. Additionally, intense sub-vortices destroyed crops in numerous fields in the area.

The tornado developed at 5:03 PM CST (6:03 PM CDT) just northeast of the intersection of Heaston and Reuter roads. Initially, the tornado moved to the southeast at 20 to 25 mph. At 5:09 PM CST, the tornado turned to the east, just south of Reno Road between Heaston and Brandley roads. The tornado continued to expand in size just southwest of the El Reno Municipal Air Park, where its speed increased to 30 to 40 mph. As the tornado passed just south of the airport, two satellite tornadoes formed briefly on the west side of the tornado.

At 5:19 PM CST the tornado crossed Highway 81 near Reno Road as it continued to expand in size. There, the tornado abruptly turned to the north, while also accelerating to greater than 50 mph. From 5:24 to 5:26 PM CST, the tornado reached its maximum in size and intensity near the intersection of Radio and Reuter roads. The tornado, still very large, slowed down as it approached U.S. Interstate Highway 40. From 5:27 to 5:35 PM CST the tornado made a loop just north of the interstate while decelerating to less than 10 mph. After 5:35 PM CST, the tornado moved east once again, and dissipated at 5:42 PM CST near the intersection of I-40 and Banner Road.

Eight people were killed in the tornado, all in vehicles. This included three severe storm researchers who were killed east of U.S. Highway 81 as the tornado overtook their position. Additionally, several other people were killed while attempting to escape the tornado near Highway 81. Finally, two people were killed along I-40 while waiting for the storm to pass.

The monetary damages were estimated. This tornado was well sampled by two separate mobile research radar teams – the University of Oklahoma RaXPol radar, and the Center for Severe Weather Research’s Doppler on Wheels. Both radars captured high temporal and spatial resolution data relatively close to the large tornado. Both radars measured winds in the tornado of more than 200 mph. The RaXPol radar data shows winds of at least 295 mph very close to the surface. These intense winds were present in very small sub-vortices within the larger tornado circulation. An analysis of the high resolution radar data combined with the results of the ground damage survey indicates that none of these intense sub-vortices impacted any structures in rural Canadian County. So despite the measured wind speeds, surveyors could not find any damage that would support a rating higher than EF-3 based solely on the damage indicators used with the EF scale.

The maximum tornado width was 2.6 miles. However, the damaging wind swath was much larger, as non-tornadic downdraft winds extended for at least a mile south of the tornado. Given the difficulty of separating this damage from tornadic damage, the OU RaXPol radar was used to help determine the width.

Ottawa/ Cherokee KS 3.4 SW Quapaw -  Quapaw - Baxter Springs KS - 2.5 NE Baxter Springs KS

The tornado began at 4:29 PM CST (5:29 PM CDT) over open country southwest of a ranch home 3.4 miles southwest of Quapaw, OK. The first damage from the tornado was that ranch home, which lost numerous shingles, a nearby barn was damaged, a mobile home had siding removed, and large tree limbs were snapped in this area. The tornado moved northeast and snapped several power poles and hardwood trees. Based on photographs, the tornado had very little condensation associated with it until it neared U.S. Highway 69a just outside of Quapaw, where it snapped trees and destroyed a barn.

The tornado then moved into the town, where it severely damaged several metal building structures, including the fire station. Numerous homes were severely damaged, and several had their roofs blown off. Several buildings in town were destroyed. Many areas of damage in Quapaw were rated EF-2.

Two people were in a vehicle that was parked against one of those buildings, in an attempt to take shelter from the approaching tornado. The brick and concrete walls of the building collapsed on top of the vehicle, crushing it and killing a 68-year-old male and injuring a female.

Several other vehicles in this area were damaged from flying debris. About a dozen injuries occurred in town, 7 of which were serious enough to warrant being transported to medical facilities. Numerous trees and power poles were snapped. The tornado continued to move northeast from Quapaw, snapping numerous trees and power poles, and damaging homes and outbuildings.

The tornado crossed the state line into Kansas at 4:25 PM CST and moved into the town of Baxter Springs, producing a 150 yard wide swath of damage from southwest to northeast through the center of town. Numerous homes and businesses were damaged or destroyed in Baxter Springs, and 25 injuries were reported. Several areas of EF-2 damage were noted, with areas of EF-0 and EF-1 damage surrounding the more significant damage swath.

The tornado dissipated at 4:42 pm CST, 2.5 miles northeast of Baxter Springs, KS. Local emergency management in Kansas reported 25 injuries with 9 of those people being hospitalized. The total path of the tornado was 7 miles in Oklahoma and another 4.3 miles in Kansas. The maximum width of the tornado was 325 yards in Oklahoma and 150 yards wide in the Baxter Springs, KS area.

Kay/ Sumner KS/ Cowley KS S of Ashton KS - Udall KS - N of Atlanta KS

At about 10:00 PM CST,this tornado touched down in northern Kay County about 4 miles north of Peckham and then moved north into Kansas. No injuries or deaths were reported, and the tornado damage was minimal in Oklahoma. This tornado was produced by the same parent supercell thunderstorm that had generated the violent tornado that struck Blackwell, OK earlier that evening.

The tornado crossed the Kansas state line due south of Ashton, KS and moved northward across the extreme eastern part of Sumner County to near Oxford, passing along the west side of Geuda Springs. At 10:15 PM CST, the tornado was located five miles south of Oxford. As is moved northward, it swung eastward around the town of Oxford to a farm three miles north-northeast of Oxford where it took the lives of five children of one family.

At 10:30 PM CST, the tornado plowed into the town of Udall, KS which had population of 500 people in 1955. It almost completely destroyed the town, killing 75 of the inhabitants, causing major injuries to 165 persons, and less serious injuries to 105 others.

After exiting Udall, the storm was reported to have moved to the east-northeastward, passing the town of Rock on the south and lifting just north of Atlanta. However, the damage east of Udall may have been caused by downburst winds. The main damage was along a path which varied in width from 1/4 to 1/2 mile. The path was irregular and indicated occasional swinging of the funnel as much as a mile on either side of a smoothed path.

Farm buildings and farm implements sustained heavy damage. No estimate was computed of the amount of crop damage left by this storm. Damage to other property was estimated at $2.225 million. This storm is still the deadliest tornado in Kansas history. Although it is listed as a F5 tornado for Oklahoma, the F5 damage produced by this tornado occurred only in Kansas.

Foard TX/ Wilbarger TX/ Tillman 2 N Thalia TX - Lockett TX - Vernon TX - ENE of Davidson

This violent tornado formed 2 miles north of Thalia, TX in Foard County. The tornado touched down 1.5 miles southeast of the first tornado produced by the parent supercell thunderstorm, which was still on the ground at 3:20 PM CST. The tornadoes traveled as a pair for 5 miles, with the second tornado continuing into Wilbarger County at about the time the first tornado ended near the Pease River.

The Wilbarger County tornado moved along and just north of Highway 70 in the Lockett area, causing heavy farm and home damage. The tornado became a killer as it crossed Highway 70 about 1 mile north of Lockett, TX. A female resident of Thalia died when her car was thrown about 200 yards off of the road into a pasture. Automobiles were also to play a major role in many of the tornado deaths later in the afternoon.

After striking the Lockett area, the tornado continued its northeastward movement toward Vernon. Photographs from Vernon show that the approaching tornado was very wide, appearing as a giant, boiling cloud on the ground. Tornado spotters had difficulty indentifying the storm at first because of its massive size. However, tornado sirens were blown several minutes prior to the storm, an action that alerted many residents to the approaching danger. Fortunately the tornado just missed the business district, but dealt a crippling blow to southern and eastern Vernon after entering the town at about 3:45 PM CST.

In southern Vernon, a multi-block residential area was destroyed, with some of the worst damage on Gordon and Atlanta Streets. At least three people were killed in their homes within this area. The tornado then moved into east Vernon where the Sands Motel, Canton cafe, a truck stop, Mechants Motor Freight, and Cardinal Equipment Building Company were all demolished. The Wilbarger Exhibit Building and the Texas Highway Department Warehouse were also destroyed.

Seven people were killed when the tornado swept a number of cars and trucks off Highway 287. The cars were nothing more than compacted masses of twisted metal after being blown off the road. After killing 10 people in Vernon and 1 in Lockett, the tornado crossed the Pease River killing a number of cows on the north bank.

After striking Vernon, Texas, the tornado moved northeast and crossed the Red River to the southwest of Davidson, Oklahoma and several miles west of the confluence point of the Pease and Red Rivers at 3:45 PM CST. The tornado moved east-northeast of Davidson and dissipated around 4:00 PM CST. At least 3 homes were destroyed with 5 more sustaining major damage. Many cattle were killed or injured. One man was injured when his car was thrown into a ditch. The tornado was on the ground in Oklahoma for a distance of 8 miles.

In its wake, the tornado left $27,000,000 in damage, with other damage coming from large hail and strong straight-line winds in the Vernon area. The tornado was on the ground for 26 miles in Texas and 11 miles in Oklahoma, with its parent thunderstorm producing three additional tornadoes in Oklahoma.

Wilbarger TX/ Wichita TX/ Tillman/ Cotton/ Comanche/ Stephens Harrold TX - 9 NNE Electra TX - Grandfield - Pumpkin Center - W of Marlow

The tornado first touched down at about 3:55 pm in the vicinity of Harrold, Texas , or about 16 miles southwest of Vernon. Two Oklahoma University meteorology students photographed the large tornado, which descended from a rotating wall cloud under the southwest flank of the severe thunderstorm.

The tornado moved across Highway 287, killing one person 200 yards west of the Texas Farm Road 1763 overpass. An official from the Texas Department of Public Safety stated that a woman had left her car to take refuge under the wheels of a semi-trailer truck when the tornado approached. She was killed when the tornadic winds caused the truck wheels to roll over her. The accident occurred on level ground, and was not the result of faulty brakes.

The tornado continued moving northeast, and caused light damage before entering Wichita County about 5 miles northeast of Harrold. Additional light rural damage occurred in the miles of Wichita County that the tornado covered. The half-mile wide tornado crossed the Red River into Oklahoma about 9 miles north-northeast of Electra at about 4:10 pm. It then began to intensify and reached maximum strength at the Grandfield Airport at about 4:30 pm. It moved northeast and crossed Highway 5 west of Walters. It continued northeast and crossed US Highway 281/177 about 11 miles south of the Lawton Airport. The tornado passed through the Pumpkin Center area around 5:30 pm and moved across Oklahoma Highway 7, where it damaged homes on both sides of the highway.

This was a very wide tornado, and 55 miles of its of 64-mile path were traversed in Oklahoma. Large hail was reported with the storm. In the Grandfield area, it damaged or destroyed 8 homes and 4 mobile homes. The Grandfield Airport was demolished, with 8 planes being destroyed and 1 damaged. Near Grandfield, 1 man was seriously injured when he tried to outrun the tornado but was overtaken. Two additional injuries were reported in the area.

Northwest of Walters, 4 houses and 1 mobile home were destroyed and 4 other homes were damaged. A grain elevator was demolished on Highway 5, and another destroyed near Hulen. In the Pumpkin Center area, 5 homes and 8 mobile homes were destroyed. Some of these homes had been hit by a tornado on April 5, 1978.

Archer TX/ Wichita TX/ Clay TX/ Jefferson 3 ENE Holliday TX - Wichita Falls TX - 4 E Byers TX - NNE of Waurika

The tornado began of the southwest flank of its supercell thunderstorm about 3 miles east-northeast of Holliday. Witnesses say the several distinct, small vortices were visible during the formative stage of the tornado as it moved along the Fort Worth and Denver railroad into Wichita County. Two oil storage tanks were blown away and several homes were unroofed near Farm Road 2650 as the tornado approached Wichita Falls. Six cross-country steel transmission towers were destroyed just east of Farm Road 2650.

About the time the tornado entered town, it changed appearance, becoming one large black cloud of condensation and debris. The tornado was about a half-mile wide when it struck Memorial Stadium, snapping light standards and causing heavy damage to the field house. McNeil Junior High school was next in the path of the tornado and the school was severely damaged. The western portion of the school building was crushed by the intense winds.

The tornado then moved east-northeast into the Western hills neighborhood, south of Southwest Parkway. Several apartment complexes and many homes were destroyed, with several of the first deaths occurring in this area. The tornado expanded in size as it crossed Southwest parkway, throwing automobiles about and leveling a number of businesses, including a bank and a fire station.

The twister was almost a mile wide when it entered the Faith Village neighborhood on the north side of the east-west oriented Southwest Parkway. Most of the homes in Faith Village were demolished. Ben Milam Elementary School was heavily damaged, as the cafeteria-auditorium was completely destroyed and exterior class rooms were pummeled by flying debris. The inner hallways would have been the only relatively safe shelter in the building. Surprisingly, very few fatalities occurred in Faith Village. Most people heeded the warnings and took shelter inside interior, small rooms in their homes. Most of the destroyed homes had some of these interior walls still standing after the tornado.

After moving out of Faith Village, the tornado flattened several businesses, including a restaurant, on Kemp Boulevard. Three people were killed in the restaurant. A number of people were also killed or injured in the parking lot of Sikes Senter (sic) Mall, also on Kemp Boulevard. Some of these people attempted to run to their cars from the mall. Inside the mall, portions of the JCPenney store collapsed while other stores sustained light to moderate damage. No one was killed and only several major injuries occurred among the appoximately one thousand shoppers who were in the mall. The mall was on the north side of the tornado path and appeared to escape the most violent winds. Near the center of the tornado and about a half mile south of the mall, a church was demolished with one person killed inside the building.

The tornado then crossed a short span of open fields before moving into the Colonial Park area. More widespread home destruction occurred in Colonial Park and several more apartment complexes were demolished. The heaviest damage in the apartments occurred in the second story of two-story buildings.

The tornado then swept through the Southmoor area, destroying homes and a shopping center. After crossing Highway 281, the twister then struck the Sun Valley neighborhood and destroyed additional homes, apartments, and businesses on the south side of Highway 287. A large number of cars were smashed and some people were killed along Highway 287. Some of these people had stopped their cars under an overpass on the highway, seeking shelter from the storm.

The tornado leveled a mobile home park on the north side of Highway 287, but residents had evacuated that area and no fatalities occurred in the park. The tornado then destroyed several industrial plants before moving into Clay County just south of Highway 79.

The tornado was 1.5 miles wide as it passed through 8 miles of residential area in Wichita Falls. The intense damage averaged between one quarter and one half of a mile in width. Forty-two people were killed outright by the storm and 3 others died as a result of heart attacks.

Further statistics reveal that 25 of the deaths were auto-related. Sixteen of these 25 were people who entered their cars trying to evade the tornado. Eleven of the 16 people left homes that were not even damaged. Eight persons were killed outside, 4 were killed in homes or apartments, and 4 others died in public buildings. Seventeen hundred injuries were reported in Wichita Falls.

Total damage in Wichita Falls was estimated at $400,000,000 (in 1979 dollars). Three thousand and ninety-five homes were destroyed and 600 were damaged. One thousand and sixty-two apartment units and condominiums were demolished and 130 damaged. In addition, 93 mobile homes were devastated. It is estimated that 5,000 families, consisting of almost 20,000 people, were left homeless in Wichita Falls.

The most damaging single tornado in history (as of 1979) continued into Clay County, resulting in no deaths, but 40 additional injuries. About $15,000,000 of damage occurred as the tornado destroyed homes immediately south of Highway 79, from Wichita Falls into the Dean and Petrolia areas.

The tornado exited Texas about 4 miles east of Byers, and crossed the Red River into Oklahoma at 6:30 pm. Over 200 trees on both sides of the river were uprooted. After crossing the river, the tornado made a gradual turn to the east-northeast and passed just to the southwest of Waurika. It then dissipated to the north-northeast of Waurika at 7:00 pm.

Heavy rain and large hail up to 3 inches in diameter were reported with the storm. The path of the tornado in Oklahoma covered 11 miles. The hardest hit area in Oklahoma was to the southwest of Waurika along Noble Wray Road. Civil Defense officials reported that approximately 20 homes were destroyed or damaged in that area. A new brick home was completely demolished. A pickup truck was lifted off the ground and smashed into a nearby car. Several mobile homes were destroyed. One frame was twisted badly and carried one quarter of a mile to the southwest of its original location.

The path length of the tornado was 36 miles in Texas, and 11 miles in Oklahoma. Minor wind damage and hail to 2 inches in diameter occurred north of the tornado track in Wichita Falls, in conjunction with the supercell thunderstorm. Also, tornado survivors said that some golf ball size hail fell prior to and immediately after the tornado.

There is no doubt that hundreds of lives were saved by the news media and siren warnings. Amateur radio storm spotters turned in the first report of the storm, which allowed 5 to 10 minutes of valuable warning time. This followed an earlier warning at 5:08 pm, due to the Rocky Point tornado. Undoubtedly, this earlier warning and the afternoon Vernon tornado had primed the Wichita Falls populace to the threat of additional tornado activity.
