A powerful storm system that tore across the United States in recent days is poised to move offshore into the Atlantic Monday, but in its wake are devastated communities across multiple states that were hit with violent tornadoes,

The dynamic storm from Friday through Sunday had earned an unusual “high risk” designation from weather forecasters.

Violent tornadoes ripped through parts of the U.S., wiping out schools and toppling semitractor-trailers in several states.

An "outbreak" of tornadoes and severe thunderstorms is expected through Saturday night in Alabama, Mississippi, Louisiana, and other southern states.
