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 cold front will slowly drop southward across the area through Monday. A strong area of high pressure will build to our north Monday and remain in place through much of the week, leading to a prolonged period of onshore flow. Several waves of low pressure may track along the stalled front to our south during this time. Small Craft Advisories will likely be needed for much of the Monday night through Thursday time period, and a few low-end Gale gusts can't be ruled out on Tuesday or Wednesday.
