SAVANNAH, Ga. (AP) A weakened but resilient Tropical Storm Elsa killed at least one person in Florida on Wednesday and injured several others when a possible tornado struck a campground at a Navy base in southeast Georgia.

The National Hurricane Center said Elsas winds have weakened to 40 mph as it made its way into southern South Carolina early Thursday. Elsa will move over South Carolina and North Carolina later in the day, pass near the eastern mid-Atlantic states by Thursday night and move near or over the northeastern United States on Friday.

Some re-strengthening is possible Thursday night and Friday while the system moves close to the northeastern United States.

A Tropical Storm Warning is now in effect north of Great Egg Inlet, New Jersey to Sandy Hook, New Jersey, and for the coast of Long Island from East Rockaway Inlet to the eastern tip along the south shore and from Port Jefferson Harbor eastward on the north shore. A warning is also in effect from New Haven, Connecticut to Merrimack River, Massachusetts including Cape Cod, Block Island, Marthas Vineyard, and Nantucket.
