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 secondary cold front will pass through tonight into Monday morning. High pressure will build in 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.
