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, then move offshore through the end of the week as a cold front approaches from the west. This front will stall near the area this weekend when a wave of low pressure may pass nearby or to the south. High pressure will likely return early next week. Small Craft Advisories may be needed at times in south to southwest flow Wednesday evening through Friday afternoon, then in northerly flow Friday night into Saturday.
