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. High pressure moves offshore tonight as a cold front approaches from the Great Lakes. The cold front will cross the Mid-Atlantic Thursday, then linger nearby Friday into the weekend as one or more waves of low pressure ride along the front stalled near the coast.
