The season’s first tropical depression was upgraded Tuesday night to Tropical Storm Arthur as it headed up the coast of the Carolinas dumping heavy rains.
The storm spent most of the day as a depression hanging off the coast. The National Weather Service upgraded it to a minimal tropical storm around 10:30 p.m., as sustained winds increased from 35 mph to 40 mph.
A tropical storm warning was posted from Edisto Beach to Cape Lookout, N.C., and a storm watch was in effect from north of Cape Lookout to the North Carolina-Virginia border.
The storm was expected to stay on that course through 11 p.m. today. It could drop up to 5 inches of rain along South Carolina’s coast.
