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 approaching the Appalachians will cross the Mid- Atlantic tonight, then move offshore Sunday morning. A secondary cold front will follow in its wake Sunday night into Monday morning. High pressure will build in behind these fronts late Monday through Tuesday. Another front looks to drop in from the north Wednesday. Small Craft Advisories may be needed Monday morning through Monday evening in northwest flow, and late Tuesday into Wednesday in south to southwest flow.
