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 weak area of low pressure will traverse the waters throughout the day today, bringing heavy showers and some thunderstorms. A cold front will move across the waters into Sunday, resulting in drier conditions returning. Weak high pressure builds over the waters for early next week bringing fair weather.
