Flash Flood Threat Returns to South Carolina Coast Over Labor Day Weekend
CHARLESTON, S.C. – After a stretch of early fall-like sunshine, South Carolina’s Labor Day forecast is turning stormy as a low-pressure system approaches from the west, bringing an elevated risk of flash flooding in the Lowcountry starting Sunday.
Saturday: Mostly Dry Except Along the Coast
Most of the Upstate and Midlands will remain dry on Saturday. However, the Lowcountry, especially the immediate coastline, faces a marginal flash flood risk, with scattered showers and possibly a thunderstorm or two.
Sunday: Moisture and Instability Increase
By Sunday, wind flow from the Atlantic will inject moisture into the region while instability from the low-pressure system increases storm chances. Numerous and widespread showers are expected, with most activity concentrated along the coast.
“The instability from the low-pressure system will be the culprit for the numerous and widespread showers,” forecasters noted.
Labor Day and Early Next Week
On Monday and Tuesday, the low-pressure system will remain east of the state but close enough to fuel instability, resulting in intense afternoon showers and thunderstorms. Flash flooding will be possible, particularly in Charleston, Beaufort, and the surrounding Lowcountry communities.
Forecasters emphasized that rainfall totals are not expected to be extreme statewide, but localized flooding could occur where heavier storms track repeatedly.
