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 wave of low pressure approaching from the Ohio River Valley will track along a stalled front over or just south of the Mid-Atlantic through Wednesday. The front will remain stalled just to the south through Thursday. Another area of low pressure may take a similar path Friday into Saturday. Small Craft Advisories may be needed Wednesday afternoon, and Friday night into Saturday.
