In Alabama's Escambia County, a tornado triggered by Claudette ripped apart at least 50 mobile homes, according to Gov. Kay Ivey.
According to Coroner Weingerlock, Butler County, 10 people, including 9 children, were killed in a two-vehicle crash on Saturday.
Five other people were hurt in the crash, but none of their injuries were critical, Butler County Sheriff Danny Bond told Reuters news agency. Meanwhile, a 24-year-old man and a 3-year-old boy were killed when a tree fell on their house Saturday just outside the Tuscaloosa city limits, Capt. Marty Sellers of the Tuscaloosa Violent Crimes Unit told The Tuscaloosa News.
The two died as drenching rains pelted much of northern Alabama and Georgia late Saturday.
"As the large circulation of Claudette moves off of the southeastern United States coast later today and tonight, winds will increase along and offshore of the coast, and the system is expected to regain tropical-storm status by Monday morning", the NHC said.
The storm also dumped flooding rains north of Lake Pontchartrain in Louisiana and along the MS coast, inundating streets and, in some areas, pushing water into homes.
The damage caused by the storm was also felt in northern Florida, where the wind (sometimes reaching 85 mph) caused the 18-wheeled vehicle to fall sideways.
A tropical storm watch remains in effect for a portion of the North Carolina coast from Cape Fear to Duck, including Pamlico and Albemarle Sounds.
"It affected everyone", Jackson said.
Forecasters said the system could still dump 2 to 4 inches (5 to 10 centimeters) of rain in the region, with isolated accumulations of 8 inches (20 centimeters) possible.
Separately, the tropical cyclone Dolores landed on the west coast of Mexico with forces close to a hurricane.
Bynum reported from Savannah, Georgia.
The NHC noted that a National Ocean Service station on Petit Bois Island, Miss. had recently recorded maximum winds of 39 miles per hour with a gust to 46 miles per hour.
The storm is expected to bring as much as 6 inches of rain to parts of the Southeast. Forecasters were warning of the potential for flash flooding and mudslides.
