Damaging Winds & Tornadoes - February 26th, 2008
Event Summary for Central Alabama
A long-lived windstorm produced by severe thunderstorms, known as a derecho, caused a widespread swath of damage across Central Alabama during the early morning hours of February 26, 2008. Although there were some sporadic reports of light tree damage and small hail west of Interstate 65, a more intense and widespread swath of damage started in southern Jefferson and northern Shelby Counties between 3:30 am and 4:00 am. From there, the damage swath moved eastward, roughly parallel to Interstate 20, reaching the Georgia border by 5:00 am. Thunderstorm wind gusts estimated at 60 to 70 mph were widespread in this damage swath, with occasional hurricane force peak wind gusts, estimated just over 100 mph in some areas.
The National Weather Service has completed an aerial survey of the damage that occurred early Tuesday morning. After combining all of the information from the aerial survey and the ground surveys conducted Tuesday afternoon... it has been concluded that... in addition to widespread severe thunderstorm wind damage... three EF-1 tornadoes touched down across Central Alabama.
As the strong cold front continued eastward, additional damaging winds occurred in Georgia, Florida and South Carolina.
