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 stationary front will meander nearby through Tuesday morning before moving south toward the Carolinas by mid-week. Special Marine Warnings will be needed at times, particularly through Tuesday. This boundary eventually dissipates later in the week. Winds shift to southerly on Thursday. Another frontal system approaches from the west by Friday.
