Charleston, SC – Thunderstorms are set to drench the Charleston area through Thursday night, bringing a renewed risk of flash flooding and hazardous driving for Lowcountry residents. Daily rounds of heavy rain and scattered storms could snarl commutes, especially in flood-prone neighborhoods.
According to the National Weather Service, showers and thunderstorms will increase after 10 a.m. Monday and persist each afternoon through Thursday. Winds may gust up to 20 mph at times, and rainfall rates could top a quarter inch per hour during stronger storms. Rain chances stay elevated at 60–70% each day, with the heaviest activity expected from 2 p.m. through late evening.
Downtown Charleston, West Ashley, North Charleston, and coastal roadways face the greatest risk for water pooling and sudden slowdowns. Low-lying stretches like Lockwood Drive and U.S. 17 may see temporary closures during peak downpours. Residents should monitor local alerts, avoid driving through high water, and keep phones charged in case of power outages.
Showers will linger overnight into Friday, then a break in the wet pattern is expected by the weekend. More advisories could be issued if rainfall totals climb quickly, so stay tuned for updates through midweek.
