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. Small Craft Advisories may be needed through Thursday as a cold front slowly crosses the waters. The front will bring scattered to numerous showers and thunderstorms this afternoon and evening. Special Marine Warnings may be needed for stronger thunderstorms during this time. Additional Small Craft Advisories will be needed Thursday afternoon and evening in northerly channeling. Increased onshore flow will keep Small Craft Advisory conditions going across the waters at times Friday into the weekend.
