Charleston, SC – Heavy rain and thunderstorms are expected to drench Charleston on Sunday, with the strongest storms arriving in the afternoon and evening. Localized flooding and dangerous lightning are possible as the region sees rainfall totals between one and two inches. Gusty winds could make driving difficult on coastal highways and low-lying roads.
According to the National Weather Service, Sunday’s storms will begin mid-morning, intensify through the afternoon, and taper after sunset. East winds at 10 to 18 mph will keep conditions breezy, while saturated ground from recent rains raises the chance of ponding water in neighborhoods and along the Charleston peninsula.
The unsettled pattern continues into Monday and Tuesday, with storms likely each afternoon and evening. While no severe outbreaks are currently forecast, repeated downpours could slow commutes, delay flights, and disrupt outdoor plans. Residents are urged to keep devices charged, avoid driving through flooded streets, and stay indoors during lightning.
The next stretch of drier weather may not arrive until late Wednesday, so those planning outdoor activities should be ready for pop-up showers and changing skies.
