Claudette was located about 80 miles west of Columbia, South Carolina, at 5 p.m. Sunday, according to the National Hurricane Center (NHC).
The storm can cause isolated tornadoes, flash floods and gusts of wind.
The tropical depression, which had maximum sustained winds of 30 mph early Sunday, is expected to strengthen into a tropical storm early Monday as it sweeps across North Carolina and the western Atlantic.
Much of North Carolina’s coast, from Little River Inlet to Duck, including Pamlico and Albemarle Sounds, is under tropical storm warning, according to the NHC.
As Claudette moves away from the east coast, a 1 to 3 foot storm surge is possible from the North Carolina-Virginia border south to Little River Inlet, South Carolina.
A tropical storm watch has been issued for parts of South Carolina from South Santee River to Little River Inlet which could see conditions deteriorate late Sunday or early Monday.
Parts of Alabama, Georgia and northern Florida will see heavy rain from the system throughout Sunday.
Claudette weakened but could regain strength
After the Gulf storm made landfall, it weakened to a tropical depression on Saturday, but downpours still hammered the region.
A total of 5 to 15 inches of rain could fall over those areas by the time the storm is over, the NHC said. As of Saturday afternoon, parts of Mississippi had received more than 11 inches of rain and parts of southeast Louisiana had received more than 8 inches, according to the weather service.
Strong winds also hit the communities. Tropical storm force winds – at least 39 mph – extended up to 205 miles southeast of the storm’s center early Saturday afternoon, the NHC said.
Alabama tornado reported on Saturday
As Claudette raged like a tropical storm on Saturday morning, a tornado hit the community of East Brewton in southern Alabama, the Brewton Fire Department said, according to the National Weather Service.
Photos of resident Alicia Jossey showed felled tree debris and other material strewn around East Brewton, a community of about 2,900 people near the Florida state border in Escambia County .
Three people in Escambia County were injured by the tornado, according to the county’s emergency management agency. The tornado also damaged several homes and law enforcement closed US Highway 29 at East Brewton due to power lines on the roadway.
“I have people’s hats on my porch and I have house frames and little things like caulk from someone working on something,” she said. “I have half of someone’s car seat in my backyard.”
