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.
Earlier, in Florence, Mississippi, 52-year-old Jacqueline Williams was on the phone Monday morning with 911, trying to direct rescuers after her vehicle went off the road into a creek, Rankin County Coroner David Ruth said. She was unable to get out and died.
