MIAMI (AP) — After bringing rains, heavy winds and even tornadoes to parts of Florida, Tropical Storm Andrea moved quickly across south Georgia and was speeding through the Carolinas early today, promising sloppy commutes and waterlogged vacation getaways through the beginning of the weekend.

The first named storm of the Atlantic season lost some intensity late Thursday and by early today its winds were down to 45 mph.

Ben Nelson, a meteorologist with the National Weather Service in Jacksonville, said Andrea was “moving at a pretty brisk pace” and could lose its tropical characteristics as early as this afternoon.

Derrec Becker with the South Carolina Emergency Management Division said the storm was near Walterboro in the southern part of the state at 6 a.m. today, moving to the northeast.

The storm had been nothing more than a severe thunderstorm so far, Becker said. No injuries were reported and there had been no reports of significant damage. Becker said some trees have been blown over.

However, forecasters warned the storm could cause isolated flooding and storm surge over the next two days.

Heavy rains were continuing well away from the storm’s center. The weather service in Charleston, S.C., advised of “an enhanced coastal flooding threat near the high tide Friday morning,” as well as of possible tornadoes. Rain bands could bring wind gusts in excess of 40 mph or 50 mph, the weather service said.

Early today, tropical storm warnings remained in effect for the East Coast from Altamaha Sound in Georgia to Cape Charles Light in Virginia, the Pamlico and Albemarle sounds and the lower Chesapeake Bay south of New Point Comfort. A tropical storm warning means tropical storm conditions are expected somewhere inside the warning area within a day and a half.

Rains and winds from the storm were forecast to sweep northward along the Southeastern U.S. coast today.
