U.S. weather forecasters warned of the threat of tornados in multiple states this weekend following at least five twisters in the state of Missouri on Friday. The tornado risk was expected to continue into the weekend in a slew of states including Mississippi, Louisiana and Alabama. Forecasters expect the thunderstorms to swamp the South and move toward the East Coast on Saturday night into Sunday. Although the tornado threat is expected to decrease, the East Coast will likely face hail and potentially damaging wind gusts. The storm system is expected to move off into the Atlantic Ocean sometime Sunday night into Monday.
