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. An area of low pressure over the Virginia Tidewater will dissipate today, with weak high pressure building over the region. A cold front will move across the waters Friday night. Small Craft Advisories for northerly channeling are possible Friday night into Saturday morning, and again Saturday evening for parts of the waters.
