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 warm front will lift northward through the area today, before a cold front moves through tonight. A strong area of high pressure will build to our north tomorrow and remain in place through much of the week, leading to a prolonged period of onshore flow. Small Craft Advisories will likely be needed for much of the Monday through Thursday time period, and a few low-end Gale gusts can't be ruled out on Tuesday or Wednesday.
