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. A weak area of low pressure will pass south of the waters later today into tonight. Brief high pressure returns Thursday with a strong Arctic front set to cross the waters Friday into Saturday. High pressure returns in the wake of this system early next week. Small Craft Advisories may be needed Thursday evening. Gale force winds are expected late Friday night through Saturday night with storm force winds possible over the open waters Saturday.
