.MARINE... North/northwest winds remain below SCA criteria today as surface high pressure builds overhead. Winds shift out of the S to SW tonight and into Friday and may near SCA criteria Friday afternoon in southerly channeling flow up the Chesapeake Bay. Confidence isn't as high at the moment, so holding off for this cycle since we are over 24 hours out, but something to keep in mind for route planning purposes. A brief period of southerly channeling is possible Saturday evening and into the night. Portions of the Chesapeake Bay could approach 20 knots during this surge. Otherwise, winds should stay below advisory criteria as the cold front passes through on Sunday. A Special Marine Warning or two are possible on Sunday as frontal showers and thunderstorms pass through. Winds shift over to northeasterly by Monday which may bring a return of Small Craft Advisories. Update as of: 1016 AM EDT Thu Jun 4 2026
