The remnants of Hurricane Katrina, one of the most devastating hurricanes in recent memory, moved over the Tennessee Valley during the evening of Monday, August 29, and the morning of Tuesday, August 30. Damage from the storm was mainly limited to trees and power lines, with some minor structural damage. The storm's main impact was felt in Louisiana and Mississippi, where it may be quite some time before affected areas can recover.

Peak wind gusts across the Tennessee Valley were "officially" in the 40-50 mph range, though there was an unofficial report of a 70 mph gust from Albertville (Marshall County). Rainfall varied widely across the area, but higher rainfall totals were found closest to the storm track across northwest Alabama. Rainfall reports ranged from 6.85 inches in Russellville (Franklin County Alabama) to zero in DeSoto State Park (DeKalb County).
