.MARINE... Light onshore flow 10 kt or less through the weekend. Overall, great boating weather through the weekend into early next week. Southerly winds pick up in intensity on Monday evening/night into Tuesday. Channeling effects could bring gusts to around 20 knots or so, which would be supportive of Small Craft Advisories, particularly across wider waters of the Chesapeake Bay. A convective threat increases through the day on Tuesday which would support the need of some Special Marine Warnings. Winds shift to northwesterly by Wednesday with gusts to around 10 to 15 knots. Update as of: 327 PM EDT Fri Jul 24 2026
