2011 Super Outbreak

The 2011 Super Outbreak was the largest, costliest and deadliest tornado outbreak ever. In 4 days, an incredible 362 tornadoes affected 21 states. The worst happened on April 27, when the storms produced damaging wind, hail and rain, along with 11 F4 and 4 F5 tornadoes that attacked Mississippi, Georgia, Tennessee and Alabama. The cost of this atmospheric wrecking ball was $11 billion, an unparalleled amount for a tornado outbreak. The fallout did not end with uprooted trees, however, as 324 people were killed and over 3,100 treated for injuries - 317 of the deaths in 1 day and 252 people in Alabama alone.
