Coastal Flood Warning Issued for St. Mary’s County

CALIFORNIA, Md. — The National Weather Service has issued a Coastal Flood Warning for St. Mary’s County. Tidal waters could rise 1 to 2 feet above ground level in vulnerable areas through early Friday morning, Oct. 3, 2025.

The warning was posted at 3:16 p.m. Thursday and will remain in effect until 4 a.m. Friday. The greatest risk of flooding is expected around tonight’s high tides.

Forecasters report that water levels are currently running 2 to 2.5 feet higher than normal. This surge could push water into roads and yards in the county’s lowest-lying waterfront communities.

At 3.5 feet, water typically spills onto roads on St. George Island. It also reaches into yards and nears structures. Similar flooding conditions are anticipated at marinas along St. Mary’s River, Smith Creek, and Jutland Creek.
