Coastal Waters Forecast

National Weather Service Baltimore MD/Washington DC

FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY.

Tidal Potomac River and Maryland portion of Chesapeake Bay. Forecasts of wave heights do not include effects of wind direction relative to tidal currents. Expect higher waves when winds are blowing against the tidal flow. Waves flat where waters are iced over. A cold front will sink southward tonight, eventually crossing the local waters by Friday morning. High pressure briefly builds over the northeastern U.S. on Saturday before another frontal system looms nearby on Sunday and into early next week. Small Craft Advisories may be needed on Friday behind the cold front. Wind gusts remain elevated at times Friday night through Monday, which may prompt additional advisories.
