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. Canadian high pressure will remain over the northeastern U.S. through the middle of the week. Another cold front is expected to near the region by Friday morning before high pressure builds in from the northwest into the weekend. Small Craft Advisories may be needed at times on Thursday due to southerly channeling effects.
