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 broad area of hot high pressure will remain near the Mid-Atlantic through the holiday weekend. The chance for strong thunderstorms remains through early next week, with Special Marine Warnings likely at times. A frontal zone will meander nearby on Sunday into Monday, before drifting south of the waters thereafter.
