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 strong area of high pressure will remain in place to our north through much of the week leading to a prolonged period of onshore flow. A strong coastal low will then develop in the Atlantic toward the end of the week. Small Craft Advisories will likely be needed for much of the Thursday through Saturday time period, and a few low- end Gale gusts can't be ruled out.
