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 warm front will slide northeast across the Chesapeake Bay tonight into early Wednesday before a potent cold front pushes through the region Thursday into Friday morning. Special Marine Warnings may be necessary tonight, mainly south of the Chesapeake Bay Bridge, as isolated thunderstorms move over the waters. Small Craft Advisories may be needed again Wednesday into Thursday with the next low pressure system and cold front.
