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 be in place for the middle to latter portions of the work week. The next frontal system pushes across the waters by late in the weekend. Small Craft Advisories may be needed on Friday night for southerly channeling, and again Sunday into Monday.
