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 slowly approach from the southwest today before a stronger cold front crosses the waters this evening. This may bring some strong to severe thunderstorms to the waterways. Behind the cold front, a trough of low pressure lingers through the remainder of the week. A coastal low tracks off the Carolinas on Saturday before high pressure builds to the southwest to finish the weekend. Small Craft Advisories are likely needed behind the cold front for much of Thursday, and perhaps again late in the weekend.
