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 south of the waters through mid week with scattered diurnal showers and thunderstorms expected in a hot and humid air mass. Special Marine Warnings may be needed each afternoon through at least Friday for strong thunderstorms moving over the waters. Small Craft Advisories may be needed Friday night into Saturday.
