The fourth named storm of the 2021 season, Danny developed into a tropical depression late Monday morning and a tropical storm by mid-afternoon. The storm was located just off the coast of South Carolina, so it had little time to gain strength before making landfall.
Tropical storm warnings remain in effect for parts of the South Carolina coastline, from Edisto Beach to the South Santee River. That zone includes Charleston.
“A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 12 hours,” according to the NHC.
It was moving west-northwest at 16 miles per hour and will bring a few inches of rainfall to the Georgia and South Carolina coasts through Tuesday. It had sustained winds of 40 mph.
“Impacts associated with it should come in the form of localized heavy rainfall, gusty winds, enhanced rip currents, and a low threat of tornadoes,” the National Weather Service in Charleston said.
The Storm Prediction Center (SPC) has issued a marginal risk – level one of five — for severe weather on the South Carolina coast, citing Danny’s intensification for the heightened tornado threat.
