April 19, 2009 Severe Weather Event

Storm surveys have been conducted examining storm damage that occurred on Sunday, April 19th.  Preliminary summaries for these surveys are found below. All tornado ratings use the Enhanced Fujita Scale.

Summary

During the late afternoon and early evening hours of April 19th, 2009, severe thunderstorms developed ahead of a cold front and moved across northern Alabama, south of the Tennessee River. These thunderstorms produced a swath of severe weather, including tornadoes, hail, and winds, as they moved eastward across the area from Franklin County through De Kalb County.

Storm Surveys

Tornado Track Map

Lawrence and Morgan Counties (Mount Hope, Moulton, Punkin Center/Neel, Priceville)

A tornadic supercell tracked across central Lawrence and west central Morgan Counties in northern Alabama between the hours of 6:00 and 7:00 PM CDT, Sunday, April 19th, 2009. Based on damage that was surveyed, much of the damage resulted from straight-line winds. However, there were four areas between Mount Hope (in Lawrence County) and Priceville (in Morgan County) that supported brief tornado touchdowns. Public Information Statement

The tornado snapped several trees along Ingram Road, at the beginning of the damage path.
A tornado touched down briefly along Hwy 157 just southeast of Moulton, and did significant damage to this warehouse.
The tornado snapped several trees along Ingram Road, at the beginning of the damage path.
The same tornado brought down a wall of this church southeast of the Moulton community.
The tornado snapped several trees along Ingram Road, at the beginning of the damage path.
Another tornado knocked a large tree down on this trailer in the Pleasant Valley Trailer Park just northwest of the Neel community. A man survived this tree fall in his bedroom on the right side of the trailer.

A tornado snapped off the trops of these trees southeast of the Priceville community.

Marshall County - Asbury Community

Rating EF-1 Peak Wind 110 mph
Path Length 3 miles Peak Path Width 75 yards

A tornado touched down just south of Gin Road in the Asbury community. A mobile home was completely destroyed with the contents blown 40 yards and the frame blown 60 yards. One occupant suffered fatal injuries with another suffering life threatening injuries. The tornado tracked northeast destroying one large chicken house and damaging several others. Many chickens were killed and two cows were killed by flying debris. Several barns and outbuildings sustained substantial damage. The tornado weakened as it continued to move northeast toward Asbury Rd with minor tree damage before it finall lifted near Old Bethel Rd. Public Information Statement

This chicken house was partially destroyed along Gin Road in Asbury.

This barn in the Asbury community sustained substantial damage.

DeKalb County - Guest Community

Rating EF-0 Peak Wind 85 mph
Path Length 1.1 miles Peak Path Width 50 yards

A tornado touched down briefly in the Guest community along County Road 50. Several trees were uprooted and a small barn was destroyed on the north side of the road. The tornado continued to move to the northeast along County Road 44 with sporadic tree damage before lifting. Public Information Statement

DeKalb County - Hammondville

Rating EF-1 Peak Wind 100 mph
Path Length 5.3 miles Peak Path Width 150 yards

Another tornado touched down along County Road 121 in Hammondville. Large trees were uprooted and a few small trees were snapped. Minor roof and structural damage was noted to a few buildings. The tornado tracked northeast with additional tree damage along Route 885. An interesting note is that a tree fell on a home along Route 885 that was also impacted by a tornado on March 28th of this year. The survey team found that the tornado lifted and touched back down periodically across northeast DeKalb County with sporadic patches of tree damage before finally lifting near the intersection of Hwy 117 and Lowery Rd.

Radar Data

This National Weather Service radar image from 6:02pm shows a rotating supercell thunderstorm moving into the Mount Hope tornado. This radar image shows the storm just before the tornado touched down. The base reflectivity product in the left panel, which shows rainfall intensity, shows a classic supercell thunderstorm. The storm relative velocity product in the right panel shows winds toward (in green) and away (in red) from the radar at Columbus Air Force Base, MS.

This National Weather Service radar image from 6:42pm shows rotation north and west of Neel around Punkin Center. The base reflectivity product in the left panel, which shows rainfall intensity, shows a Bounded Weak Echo Region (BWER), or an area of lower reflectivity values entirely surrounded by high reflectivity values. This is indicative of rotation and the presence of a mesocyclone in the storm.
