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 cross the waters early today before settling over the southeastern U.S. later in the weekend. High pressure will build quickly north and east of the area Sunday before a warm front moves through later that evening. Next week, high pressure builds to the south while a frontal zone remains over the Great Lakes into New England. Small Craft Advisories may be needed Sunday night through Monday evening.
