A severe weather threat is moving to the Southeast and East Coast on Sunday after deadly tornado-spawning storms pummeled Texas and Mississippi, tearing through homes and leaving at least two people dead.

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.

Officials were beginning to assess the damage after a strong storm system moved across the southeastern U.S. over the weekend
