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 cold front will slowly push southeastward through the area between this afternoon into tonight. Low pressure will ride along the boundary to our south on Monday. High pressure will build in from the west on Tuesday before another frontal system approaches Wednesday. Small Craft Advisories may be needed again at times Monday night through Tuesday morning and again Wednesday through Thursday.
