.MARINE... A multi-day period of hazardous marine conditions are looking likely for the week. Behind a potent cold front, a gusty northwesterly wind up to 20 to 25 knots will persist throughout the day. Consequently, Small Craft Advisories are in place for such winds before gale conditions move into the picture tonight through Tuesday evening. A sharpening trough sweeps through the area early Tuesday which yields a secondary surge in winds. Gale Warnings have been hoisted up for the expected 35 knot west-northwesterly gusts. Given a healthy wind field aloft, occasional 40 knot gusts are possible over the more southern waters. Winds eventually switch over to southwesterly late Tuesday into Wednesday. Small Craft Advisories will again be needed during this period with gusts up to 25 knots. Small Craft Advisories will likely be needed Thursday in the wake of a weak cold front. Westerly gusts of 20-25 kt are expected. Winds will finally weaken Friday as high pressure moves overhead. Update as of: 400 AM EST Mon Nov 10 2025
