Tropical Storm Helene was expected to build into a major hurricane by the time it comes ashore Thursday/National Hurricane Center

Editor's note: This adds portions of Gulf Islands National Seashore and closures in areas of the Blue Ridge Parkway, Great Smoky Mountains National Park, Ocmulgee Mounts National Historical Park, Congaree National Park, and national park sites in Georgia and South Carolina to areas of the National Park System closing in advance of Helene, as well as Helene's status.

Prior to Helene's landfall, Cumberland Island National Seashore on the Georgia coast closed, as did portions of Gulf Islands National Seashore on the Mississippi-Florida coast. Fort Pulaski National Monument, despite its location on the Georgia coast to the east of the main storm track, planned to close Wednesday at noon, and portions of the Blue Ridge Parkway in North Carolina and Virginia initiated closures Wednesday afternoon and Thursday morning. Fort Frederica National Monument on the coast of Florida closed Thursday "due to predicted rainfall, winds, increased chance of tornadoes and flooding conditions from this storm. Great Smoky Mountains National Park in North Carolina and Tennessee implemented closures as well.

Ocmulgee Mounds National Historical Park in Georgia closed on Thursday as did Congaree National Park and Fort Sumter and Fort Moultrie National Historical Park and Charles Pinckney National Historic Site, all in South Carolina.

"A mandatory evacuation is in place," the park staff at Cumberland Island said. "All campers, visitors, staff, and volunteers must depart the island on the 2:45 p.m. or 4:45 p.m. boats on Tuesday, September 24. The last boat departing the island is at 4:45 p.m. from the Sea Camp dock."

Until further notice, the rest of visitor use areas within the Gulf Islands' Florida District were to remain open for day use.
