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 briefly build overhead late today. A warm front will slowly approach from the southwest Thursday. An area of low pressure will traverse the boundary Friday as it stalls across the Ohio Valley and Carolinas. A stronger cold front will arrive toward the end of the weekend. Intermittent Small Craft Advisory conditions are possible Thursday and Thursday night. Small Craft Advisories will likely be needed by late Sunday.
