Weather History: April 24th, 2010 Intense Tornado Outbreak

From April 24th, 2010 the region is supporting a severe weather event. This unstable air was funneled in from the south during the 23rd and 24th. There was a wind shear, turning at different levels of the atmosphere, to support tornadic development. A strong low-pressure system passed to the north of the region but the shortwave trough associated with it tracked through our region.

Instability, lift, and wind created a favorable environment for severe storms to develop. Storms started firing up in northwest Alabama during the afternoon hours. Of these storms tracked eastward, they encountered a favorable environment allowing them to rapidly intensify. Supercells that tracked across northern Alabama produced heavy rainfall, hail, gusty winds, and even tornadoes. Four strong tornadoes touched down that day in our area, one of those being the EF4 tornado. In total, 12 touched down in Alabama with 52 individuals sustaining injuries.

EF4 and Long Track Tornado

The most destructive tornado to touch down that day was an EF4 tornado that tracked through DeKalb County. The tornado touched down west of Hendrixville in the southern portions of the county and then tracked northeast for just over 16.5 miles. The tornado was on the ground for 30 minutes and produced significant damage in some locations. The tornado lifted near the Dog Town community.

It was in this area that the tornado was most intense, with a peak winds estimated to have been 170 mph. Along with this damage, several trees were uprooted or snapped, and the Dog Town community, homes sustained structural damage before the tornado lifted.
