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 shifts northeast towards New England through this evening. The next frontal system approaches from the northwest on Monday before moving through on Tuesday. The associated cold front should cross the waters by late Tuesday before weak high pressure slowly builds in by mid-week. Small Craft Advisories may be needed Monday evening into Tuesday due to southerly channeling effects.
