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 strong cold front crosses the area this evening. A line of strong to severe thunderstorms is expected to cross the waters this afternoon to evening. Dangerous wind gusts in excess of 50 knots and waterspouts are possible. High pressure returns for the middle to latter portions of the week. Small Craft Advisories will likely be needed through Tuesday. Gale conditions are also possible through late tonight.
