Latest Marine Discussion:

.MARINE... High pressure overhead today should yield light winds, with no marine hazards expected at this time. Wind gusts early Wednesday will be sub-SCA criteria before another ramp up ensues for the second half of the day. Southerly channeling effects will likely warrant Small Craft Advisories across portions of the waters through Wednesday night. With the cold front not arriving until late Thursday, there are some hints of some 15 to 20 knot southerly gusts on Thursday. This also comes with the risk of stronger convection, many capable of needing Special Marine Warnings. Scattered showers & thunderstorms Friday could also create locally gusty winds over the waters, perhaps necessitating a few SMWs. Saturday and Sunday look to be dry for the most part with winds below SCA criteria. Update as of: 334 AM EDT Tue Aug 25 2026
