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. Arctic high pressure will gradually build into the area late tonight into Tuesday before moving offshore Wednesday. Freezing spray is possible tonight. Small Craft Advisories may be needed Tuesday night for portions of the waters in southerly channeling. Then SCAs are likely Thursday into Thursday night ahead of a strong cold front passage, with Gale-force winds not out of the question.
