The deadly storm Claudette strengthened Monday morning to regain its tropical storm status as it approached the Carolina coast.
Thirteen people in Alabama died Saturday in storm-related conditions, including eight children in a multi-vehicle crash.
The children who died were in a van for a youth home for abused or neglected children. The vehicle crashed and burst into flames on Interstate 65 about outside of Montgomery, according to the Associated Press.
An official said the vehicles likely hydroplaned.
The two other victims in the weekend crash have been identified as Cody Fox, 29, and his 9-month-old daughter, Ariana; both of Tennessee. They were in separate vehicles from the van, the wire service also reports.
