| A Review of Weather in 2002 |
The year 2002 had its share of interesting weather phenomena in Tallahassee and surrounding areas. Following are a few of the weather highlights that occurred in the NWS Tallahassee County Warning & Forecast Area in 2002.
Snow Flurries & Roller Coaster Winter Temps
As can be seen in Figure 1 (below), the year started out on a very cold note. The first week of 2002 saw the first snow flurries officially observed in Tallahassee since March 1996. Snow occurred twice on January 3rd. Large flakes fell briefly around 5:30 AM with several areas seeing small snow pellets during the late afternoon hours. Dothan, AL, and Albany and Valdosta, GA, also reported flurries that day. Another brief period of flurries occurred in Tallahassee on January 7th. Temperatures during the first nine days of the month averaged well below normal with subfreezing temperatures in Tallahassee on six of the first nine mornings. The low of 19 on the 5th broke the record for the date. A period of very mild weather commenced on January 18 and continued until February 1, when the mercury reached 80 degrees in Tallahassee and 83 in Valdosta. After a period of fairly normal winter weather, a late season arctic outbreak brought the coldest temperatures of the season to the region from February 27 through March 5. The low of 18 on the morning of the 28th was the coldest temperature of the year in Tallahassee, a record for the date. Albany recorded 18 that morning. Record lows were also recorded in Tallahassee on March 1st and 5th. The coldest afternoon of the year occurred on March 4th with a high temperature of just 41 degrees.
Very Warm Spring
The late season cold snap ended abruptly with the last freeze of the seaon in Tallahassee occurring on March 6th. Most of the Spring season averaged well above normal with April being the warmest on record in Tallahassee. Temperatures reached 80 or better on 12 of the last 17 days in March. The first 90 degree temperature of the season occurred April 18th and there were five other such days during the month. Nighttime lows were very mild. After the 7th, the temperature never fell below 57 degrees in April. The hot weather continued into May with twelve of the first 13 days exceeding 90 degrees. Record highs were tied on May 3rd and 9th. A brief cool period commenced on the 14th and continued to the 24th. The mercury dipped below 50 in Tallahassee on the 20th and 21st with a record low set on the 21st.
Typical Summer Temperatures
Temperatures were fairly typical during the summer months. Temperatures averaged about a half a degree cooler than average for the season. Hot spells occurred in early June and mid July, with the latter being the hottest of the season. The temperature reached 100 degrees on two consecutive days in July. On the 18th, the mercury officially reached 100 degrees at the Tallahassee airport for the first time since July 20, 2000. Both Albany and Apalachicola reached the century mark that day as well. The high of 101 in Tallahassee the next day was the hottest temperature of the year. Panama City FL, Dothan AL and Valdosta GA all reached 100 degrees that day as well. During the second weak of August, a front swept in the from the north bringing an unusual break from summer's typical unending humidity. The dry air allowed overnight temperatures to drop to comfortable levels on the 9th and 10th with record lows of 60 and 64 established respectively. The low of 60 on the 9th was the coolest ever recorded so early in the season. That morning saw the mercury dip to 58 in Valdosta, with record lows of 58 at Perry FL, 57 at Cross City FL, 62 at Albany and 69 at Apalachicola. No record high temperatures were set during the summer months.
Hot Early Autumn - Cold Late Autumn/Early Winter
Summer's heat continued into the early part of Autumn. Temperatures reached or exceeded 90 degrees on five of the first seven days in October. The record high of 94 on the 6th was just a degree shy of Tallahassee's all-time October maximum temperature of 95 set October 1, 1933. Apalachicola set a record high of 90 on the 13th. A brief cool spell occurred mid month with the only below normal days in Tallahassee occurring consecutively from the 15th through 19th. However, the lowest temperature recorded was just 46 degrees on the 18th and 19th. The month averaged nearly five degrees above normal. The warm weather continued into the second week of November with a record high of 86 recorded on the 11th. Apalachicola set a record high of 82 on that date. Wintery temperatures set in after that. The first official freeze occurred on the 18th with a low of 32 in Tallahassee and Albany, and 31 at Valdosta. The first widespread freeze occurred on the 23rd. There were a total of four mornings with temperatures at or below freezing for the month with the coldest temperature of the season in Tallahassee (25) setting a record for the date on the 29th. Apalachicola set a record that morning as well at 31 degrees, the first freeze of the season for that coastal city. The cold weather continued through most of December with a dozen days reaching the freezing mark or lower in Tallahassee. Overall, the two months averaged over three degrees colder than normal.

Rainfall Deficit Continues
After near normal precipitation in 2001, Tallahassee ran a rainfall deficit for most of 2002. As can be seen in Figure 2, with the exception of a single torrential rainstorm in early March (see discussion below), the rainfall deficit grew steadily through the first half of the year. Frequent rains occurred in January, but February precipitation was just 1/3 of normal. The period from April through June was quite dry, with only two significant rainfalls during that time. During the driest stretch, no measurable rain fell in Tallahassee from April 20 through May 17, a period of four weeks. By the end of June, the rainfall deficit was running about ten inches. The second half of the year had near normal rainfall on average. However, August was abnormally dry. The greatest deficit of the year was reached on September 11. Heavy rains associated with Tropical Storm Hanna drenched the area in mid September (see discussion below), and the remainder of the year saw near normal precipitation. The annual rainfall total in Tallahassee was 56.10 inches, which was 7.11 inches below the 1971-2000 normal.
Early March Flooding Across the Florida Big Bend
Heavy rains fell across the region on March 2nd and 3rd with nearly 8.5 inches of rain falling in Tallahassee in just 24 hours. Valdosta got nearly five inches from the same system, but much less rainfall occurred further north and east. Widespread flooding occurred across much of the Florida Big Bend and Eastern Panhandle. In Calhoun County, about 80 percent of the county's dirt roads were closed due to flooding. In Leon County, an estimated 90 homes sustained significant water damage. Several residences in the Carriage Estates mobile home park were evacuated due to high water. Numerous motorists were rescued from stranded vehicles. Many Tallahassee streets and county roads were closed. Similar flooding was reported in Wakulla, Jefferson and Madison counties.

Tropical Storm Hanna
Tropical Storm Hanna passed over southeastern Louisiana near the mouth of the Mississippi River early on September 14th and made landfall near the Alabama-Mississippi border around midday with 50 mph winds. The strongest winds locally were observed at Cape San Blas, FL. At 4:00 AM EDT, the wind at the Cape was blowing out of the south at 41 mph, with gusts to 55 mph. Peak winds across inland portions of the Florida Big Bend and Eastern Panhandle were generally 30-35 mph. Wind damage occurred in Walton and Jackson Counties in the Panhandle, and Seminole County in Southwest Georgia. There was a four-foot storm surge in Walton County, with tidal departures of three and two feet in Bay and Gulf Counties, respectively. Dangerous rip currents were responsible for two deaths. Two adult men drowned, one near Seagrove Beach on the 14th, and the other at Panama City Beach on the 15th. The main impact from this storm on the local area was the flooding rains. Rainfall totals were generally 5 to 7 inches across the eastern Panhandle and western Big Bend in Florida, as well as across southwest Georgia. Two- to four-inch totals were common further north and east. The greatest rainfall from the storm anywhere in the U.S. occurred in Donalsonville, GA, which is in Seminole County in extreme southwest Georgia. Heavy rains kept training over this location and produced an incredible 15.56 inches of rain. This flooded numerous homes in the area, as well as U.S. Highway 84. Nearby Spring Creek crested above flood stage. Elsewhere, flooding occurred in adjacent areas of Jackson County, FL, and Miller County, GA, as well as in Perry, FL, and along the St. Mark's River. Fortunately, Hanna spawned no tornadoes in the area. Additional information on Tropical Storm Hanna can be found here.
Tropical Storm Isidore
On September 26, Tropical Storm Isidore made landfall well west of the area, along the Louisiana coast just west of Grand Isle. However, Isidore was a hybrid system and therefore displayed characteristics of both a tropical and extratropical system. The result was that the maximum winds and heaviest rains extended well away from the storm's center. Peak winds locally were even higher than those from Hanna. Because Isidore was a major hurricane while it skimmed the Yucatan Peninsula, large swells were generated which propagated north across the Gulf of Mexico. The combination of wind and wave action produced larger storm surge than would normally be expected with a tropical storm, along with some coastal flooding and severe beach erosion along the coast. Cape San Blas once again recorded the highest observed wind in our region. At 4:00 AM EDT, the wind was clocked at 46 mph out of the southeast with gusts to 58 mph. Most inland stations had peak winds of 30-40 mph. The buoys moored about 80-90 miles off the coast recorded peak seas of 19-24 feet. A 5-7 foot storm surge removed about 400, 000 cubic yards of sand from the Walton County coast, resulting in about $4 million dollars damage. A 5-foot surge removed even more sand from Bay County beaches. Storm surge of 3-4 feet also caused substantial beach erosion in Gulf, Franklin, and Wakulla Counties. On Dog Island, two houses partially collapsed and several others were damaged. Fortunately, there were no rip current deaths reported. Two tornadoes touched down in Walton County. One twister damaged several mobile homes in Santa Rosa Beach. Another tornado damaged numerous homes in Sandestin near U.S. Highway 98. Further inland, four homes were damaged in Graceville in Jackson County, FL. One person was injured there. At Bonifay in Holmes County, FL, there was damage to the roof and a school bus at Poplar Springs High School. The greatest rainfall total occurred in Geneva, AL, were 5.6 inches of rain fell. Most other areas got 1-3 inches. Additional information on Tropical Storm Isidore can be found here.
Severe Weather
Typically, this part of the country sees a peak in severe weather activity during the spring months with a secondary maximum in November. Through summer, isolated severe storms are possible on almost any day, although large outbreaks are much less common. Occasionally severe weather occurs in the winter months, and some of these can be major outbreaks. In 2002, there were several severe weather episodes during spring and above average activity in the fall. However, the biggest severe weather outbreak of the year occurred during a winter month.
