Ian has weakened to a tropical storm with winds of 65 mph and higher gusts, according to the 5 a.m. update from the National Hurricane Center.
Tropical Storm Ian is still expected to produce strong winds, heavy rains, and storm surge across portions of Florida, Georgia, and the Carolinas over the next 3 days, the center said.
A storm surge warning is in effect for the St. Johns River in northeast Florida, as well as areas stretching from the Flagler-Volusia County line in Florida north to the South Santee River in South Carolina. Portions of the Gulf Coast also remain under storm surge threat.
Tropical storm warnings have been issued for much of Florida's Gulf Coast, from north of Bonita Beach up to Indian Pass along the Panhandle.
Areas stretching from Boca Raton to Cape Lookout, North Carolina, also face a tropical storm warning, as does Lake Okeechobee. Some isolated hurricane-force winds may still occur.
