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 remains positioned north of the area through the middle of the week as low pressure meanders off the Mid-Atlantic coast. The low will likely depart by the end of the week as high pressure builds overhead. Additional Small Craft Advisories will likely be needed at times through the end of the week.
