Charleston, South Carolina – A slow-moving coastal low is expected to drench parts of South Carolina through Thursday, bringing the potential for localized flooding, dangerous beach conditions, and gusty winds from Charleston to the Georgia border.
According to the National Weather Service in Charleston, the system began forming near northeast Florida early Wednesday and will move inland, dropping 1 to 3 inches of rain along and east of I-95. The highest rainfall is likely in the Charleston Tri-County area, with isolated pockets seeing over 5 inches. Rain bands will continue into Thursday, raising concerns about ponding in low-lying areas and blocked drainage systems.
Winds up to 40 mph could hit coastal counties, especially around the beaches, though confidence in widespread wind damage remains low. However, the biggest concern for beachgoers is rip currents—conditions are already elevated and may increase further through the end of the week.
A Small Craft Advisory is in effect from the South Santee River to Altamaha Sound due to 3–6 ft seas and sustained east-to-southeast winds at 15–20 knots.
Residents are urged to avoid flooded roads, secure outdoor items, and stay off beaches during hazardous surf.
The next full weather briefing is expected by 6 p.m. Wednesday. More advisories could follow if the system strengthens.
