.MARINE... Gusty west to northwest winds are expected through today. A Gale Warning remains in effect until 6 AM for all of the waters. For the rest of today, the strongest winds will most likely be over the upper Tidal Potomac River and northern Chesapeake Bay. A Gale Warning continues through this afternoon for these areas (gusts around 35 to 40 kts) and an SCA is in effect for areas to the south. Even across these areas, gusts around 30 knots are expected and a few gusts around 35 knots cannot be ruled out. Winds will continue to gradually diminish over the waters tonight, but an SCA is in effect for all of the waters this evening and for the Bay/lower Tidal Potomac River overnight. An SCA is in effect for the waters Wednesday ahead of an approaching cold front and the SCA will likely be needed Wednesday night as well. The cold front will pass through late Wednesday night into Thursday and more gusty northwest winds are expected behind the cold front. An SCA will likely be needed for the waters with gusts around 30 knots possible. High pressure will build overhead later Thursday night into Friday, bringing lighter winds. Update as of: 322 AM EST Tue Dec 30 2025
