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 remain overhead today. A period of southerly channeling may result in brief Small Craft Advisory conditions Tuesday afternoon and evening, but given the short duration it may be best handled with a Marine Weather Statement. High pressure will shift to the south the second half of the week. A weak cold front will drop southward Thursday into Friday, then a stronger cold front will approach from the north Saturday.
