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. High pressure will build near the area over the weekend before a frontal system approaches the area Monday. Small Craft Advisories will likely be needed for portions of the waters Monday night into Tuesday. Special Marine Warnings may be needed as thunderstorms track over the waters Monday afternoon and evening.
