CHARLESTON — A flash flood warning has been extended on the South Carolina coast.


The National Weather Service says the warning will remain in effect through Friday afternoon in the immediate Charleston area. The warning means flooding is imminent or highly likely and was scaled back a bit after an earlier warning for Charleston, Berkeley and Dorchester counties.


Heavy rains drenched the area Thursday, with some places receiving up to 8 inches. Numerous streets in the Charleston area were closed because of flooding but all have reopened.


Meanwhile, a flash flood watch is posted for the Pee Dee and the north coast through Sunday evening. It means conditions are favorable for flooding.


The National Weather Service in Wilmington predicts 2 to 4 inches of additional rain, with some areas receiving 6 inches.
