Most of the destruction happened on Wednesday, April 27, when atmospheric conditions came together across the South to produce ideal conditions for long-track tornadoes.
The outbreak was not a surprise to meteorologists at the Storm Prediction Center, who issued a high risk (5 out of 5) threat and placed the bull's-eye zone over northeast Mississippi, south Tennessee and northern Alabama.

A series of squall lines produced many of the tornadoes throughout the day, but where storm cells were able to tap into the unstable environment, they produced strong, long-track tornadoes.
One of the most destructive twisters was an EF-4 that hit populated areas in Alabama that included Tuscaloosa and Birmingham.
An EF-4 that was 1.5 miles wide traversed 80.3 miles through Alabama and impacted the cities of Tuscaloosa and Birmingham.

The tornado is believed to have stayed on the ground for 80 miles and had winds around 190 mph at its peak.
Immediately after the storms, Jeff Byard, an executive operations officer for Alabama Emergency Management, said he knew the scope of the damage from unfathomable.
"It soon became very apparent that the state could not handle the emergency alone. It will go down in history as the worst outbreak of tornadoes in Alabama," Byard said.
