.MARINE... Generally lighter westerly winds are expected today, though deeper mixing and a marginal wind field could result in sporadic 15-20 knot gusts this afternoon over the northern waters. A warm front will lift across the waters Saturday, and winds will shift to the south by then. Channeling likely pushes gust into the 20-25 knot range by Saturday evening ahead of an approaching cold front, then winds shift to the west/northwest and gust up to 30 knots through Sunday. Brief/sporadic gale conditions can't be ruled out both with the immediate frontal passage overnight Saturday night, then again during the day on Sunday in the wake of the front. Somewhat lighter winds are forecast Sunday night, though SCA conditions likely persist for most of the waters. Small Craft Advisory conditions appear likely within northwesterly flow on Monday. Sub-SCA level winds are expected on Tuesday. Update as of: 227 AM EST Fri Nov 14 2025
