Latest Marine Discussion:

.MARINE... Conditions across the marine waters are likely to remain favorable through much of the holiday weekend. Northerly winds may gust to around 10 knots or so this afternoon, while winds eventually shift to south-southeasterly for the weekend. The flow around high pressure off the Atlantic begins to pick up by Sunday evening. Small Craft Advisories may be needed for Sunday evening into Sunday due to southerly channeling effects, especially over the more southern waters. Showers and thunderstorms are possible over the waters as a cold front approaches the forecast area next week. Winds are expected to stay below SCA criteria both Monday and Tuesday, although SMWs are possible during afternoon showers and thunderstorms. Update as of: 336 PM EDT Fri Jul 4 2025
