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. High pressure will continue to strengthen offshore today through Tuesday leading to increased south to southwesterly flow. Expect Small Craft Advisories for channeling this afternoon and again Tuesday afternoon. Winds will subside during the late evening and overnight periods. Additional Small Craft Advisories will be needed Wednesday into Thursday as a cold front crosses the waters. The front will bring scattered to numerous showers and thunderstorms Wednesday afternoon and evening. Special Marine Warnings may be needed for stronger thunderstorms during this time.
