At least three people have died as severe thunderstorms batter the Southeast and East Coast on Sunday after deadly tornado-spawning storms tore through Texas and Mississippi, ripping off roofs and flattening homes.

The National Weather Service said it confirmed several tornadoes had touched down outside of Houston on Saturday, as two people died. More severe weather is expected across the U.S. on Sunday.

Heavy rain and severe thunderstorms capable of producing tornadoes, damaging wind gusts and hail are likely across the eastern Gulf Coast—including portions of southern Georgia, Alabama and Florida—and into North and South Carolina, where a severe thunderstorm warning is in effect, the National Weather Service said.
