Overview
Between August 22-23, 2025, numerous to widespread showers and thunderstorms produced heavy rainfall across the South Carolina Lowcountry and southeast Georgia as a cold front stalled over the region. This boundary caused widespread flash flooding, which was intensified by soils already saturated from heavy rain earlier in the month. Flooding along the coast was exacerbated by high tide, with the Charleston Harbor Tide Gage reporting periods of moderate coastal flooding. The event led to numerous road closures, inundated vehicles, and flooded structures, and also set new rainfall records — including at two of our climate sites, as shown in the images below.

Moderate to heavy rainfall coupled with saturated soils resulted in widespread flooding across our area on August 22-23, 2025. Some of the more notable impacts occurred along the coast, where high tides resulted in periods of moderate coastal flooding, as seen in the Charleston Harbor Tide Gage image below. Periods of minor coastal flooding were also noted on the Fort Pulaski Tide Gage.
