A string of deadly storms that ravaged some Southern states over the weekend could put millions more at risk as it moves north Monday (May 1).

At least 13 people were killed and dozens more injured as storms tore through Texas, Missouri, Arkansas, Tennessee and Mississippi over the weekend, spawning tornadoes and floods that left a trail of devastation, reports the CNN.

Tornadoes tore roofs off homes, ripped trees out of the ground and tossed cars “around like toys,” one witness said. Floods swept cars off the road and downed trees and power lines that flattened homes.

The storms were expected to move into Alabama Sunday evening and continue along a path extending to Michigan. A severe weather warning is in effect through Monday, putting 22 million people in six states from North Carolina to New York at risk of isolated tornadoes, high winds and large hail.

At least three tornadoes touched down in northeast Texas on Saturday, leaving widespread damage in Van Zandt and Henderson counties, a rural area about 60 miles east of Dallas.

At least four were killed and 49 people were taken to area hospitals, Canton Mayor Lou Ann Everett said. One person is still unaccounted for. 

First responders from across the state went door to door on Sunday to look for survivors in more than 5,000 homes in the tornado's path, she said.
