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 build across the Mid-Atlantic through Wednesday. A cold front will cross the area Wednesday night. A second cold front will cross the region Thursday, with a third set to cross Friday. Arctic high pressure will build across the Midwest, Great Lakes and Northeast this weekend as low pressure develops and lifts up from the south. Small Craft Advisories will likely be needed Wednesday into Wednesday night, and may be needed late Friday into the weekend.
