The National Weather Service says 2 to 4 inches of rain could fall across much of the state through Saturday. The heaviest rains are expected near the coast, where the center of Andrea is expected to move.
The heavy rains come after an especially wet spring, and forecasters say flooding is a distinct possibility. They are asking people to keep an eye on the weather over the next few days.
The National Hurricane Center issued a tropical storm watch for Andrea along the entire South Carolina and Georgia coasts.
