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 build in through Tuesday. A weak cold front looks to drop in from the north Wednesday, then cross the Mid-Atlantic by Thursday. Small Craft Advisories may be needed late Tuesday into Wednesday in south to southwest flow. Additional Small Craft Advisories are possible later this week and weekend as multiple fronts and waves of low pressure traverse the region.
