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 build in today. Another cold front will push through Sunday night before high pressure approaches from the west early next week. Small Craft Advisories may be needed Saturday morning, and again Sunday afternoon through Monday night. Depending on how the thunderstorms evolve Sunday evening into Sunday night, Special Marine Warnings are also possible.
