(CNN) At least five people have died as a severe storm system swept through several Southern states.

In South Carolina, Jason Matthews, 66, died Monday when strong winds flipped his mobile home several times, Union County Sheriff David Taylor said.

"He was barely alive when (his) brother found him. By the time EMS and law enforcement could get to him he had died from his injuries," Taylor said.
