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 frontal zone will meander about the Mid-Atlantic through Friday. Another cold front will push south across the waters this weekend before settling south over the Carolinas by early next week. Special Marine Warnings may be needed for strong to severe thunderstorms through Saturday, but especially this afternoon and evening.
