The National Park Service is closing campgrounds on the southern end of the Cape Hatteras National Seashore in preparations for Tropical Storm Hanna.
Cape Hatteras National Seashore spokeswoman Cyndy Holda says the campground and visitors center on Ocracoke Island will close at 5 p.m. Thursday.
The campground at Frisco on Hatteras Island also will close.
Ocracoke is reachable only by boat, and Hatteras Island can be reached by boat or over a single two-lane bridge over Oregon Inlet.
Holda said officials would decide later whether to close facilities north of Frisco.
The forecast track for Hanna takes the storm over a portion of the
Outer Banks where the park is located.
