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 be persistent off the east coast into the middle of the week while a cold front gradually approaches from the north. Daily thunderstorm chances continue for the remainder of the week. Gusty winds and frequent cloud to ground lightning will be the primary threats with any storms. Special Marine Warnings will be a possibility each day today through Friday.
