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 slow moving cold front will cross the waters this morning before the boundary settles over the Carolinas on Saturday. The front returns northward as a warm front late in the weekend before another cold front crosses the region by Monday. High pressure returns for early next week. Expect some Small Craft Advisory level channeling this upcoming weekend, mainly over the open waters.
