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. An area of high pressure will build near and south of the Mid- Atlantic through the week. A pop up shower or thunderstorm can't totally be ruled out near any bay or river breezes each afternoon, though most of the time should be dry until Friday when the high pressure begins to shift. The chance of strong thunderstorms will increase Friday into the weekend. Southerly channeling may require the issuance of Small Craft Advisories at times through Wednesday.
