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 Nor'easter will develop offshore and intensify as it lifts northward into this weekend. High pressure will eventually build into the area early next week. Small Craft Advisories and potentially gale conditions will continue through Sunday. Advisories may be needed through Monday.
