Drone video shows the power of a tornado's 120 mph winds in Alabama where a school bus was lofted onto a high school gymnasium.

Officails say 52 of Alabama’s 67 counties sustained damage from severe weather Saturday evening, but Shelby and Talladega counties were hit particularly hard in certain spots. A tornado threw a school bus onto the roof of Winterboro High School gymnasium as it tore through Talladega County on its way east.
