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 coastal low will develop offshore and intensify as it lifts northward into this weekend. Small Craft Advisories will likely be needed for much of the Friday through Saturday time period, and a few low-end gale gusts can't be ruled out. A Gale Watch is in effect for the southern waters Friday afternoon through early Saturday afternoon.
