3-6 inches of rain likely in coastal SC area as tropical disturbance looms

A tropical storm watch and flash flood watch are currently in effect for the northern coastal areas of South Carolina with an incoming system that will likely bring heavy winds along with three to six inches of rain.

A potential tropical cyclone may bring heavy rain and gusty winds to portions of coastal South and North Carolina, according to the National Hurricane Center’s public advisory 8 a.m., update.

The storm is currently 135 miles south-southwest of Charleston with sustained winds of 35 mph, according to the advisory. As of 8 a.m., the disturbance was stationary. The discussion by forecasters said its expected movement this afternoon will be little and erratic.

There may be heavy winds as the storm’s center moves by, along with three to six inches of rain in the upper coastal areas of South Carolina. There may be some isolated parts that may produce as much as 9 inches.

“Some strengthening is possible during the next 48 hours, and the system is expected to become a tropical storm by Tuesday morning and then become post-tropical by Tuesday night,” the 8 a.m., advisory said.

The heavy rainfall can lead to ponding water or road closures, and rivers and streams may rise and overspill their banks in some places, according to officials.

“Underpasses, low-lying spots along roadways, and poor drainage areas may become submerged by rising water,” the briefing says.

Hazardous boating conditions, steep waves near inlet entrances, dangerous rip currents and surf is also expected for the coast through Tuesday morning.
