According to a National Hurricane Center public advisory posted at 11:00 a.m., a hurricane warning had been downgraded to a tropical storm warning for the Gulf Coast of Florida from Bayport northward, and westward to the Ochlockonee River. All warnings south of Bayport were discontinued.

“A tropical storm warning remains in effect for the Gulf Coast of Florida from Bayport to Indian Pass,” the advisory said. That warning also remained in effect along the Atlantic Coast from Flagler Beach, Fla., to South Santee River, S.C.

At 11:00 a.m., the center of Tropical Storm Alberto was about 50 miles southeast of Tallahassee, Fla., just offshore of Keaton Beach, Fla.  The storm’s maximum sustained winds were near 50 mph, with higher gusts. The advisory predicted coastal storm surge flooding of five to seven feet above normal tide levels to the east and south of where the center makes landfall. Four to eight inches of rain could be dumped on affected regions.

The advisory said that isolated tornadoes were possible today over portions of northeastern Florida, southeastern Georgia, and coastal South Carolina
