.MARINE... Southwest winds are expected to increase through today. This will provide an environment for Small Craft Advisories for portions of the waters by late this afternoon and most waters tonight. High end advisory conditions are likely today as strong low pressure passes to the north. Gale Warnings are in effect for the northern Chesapeake Bay. The strongest gusts will be near the shore as air temperatures rise into the 90s. Special Marine Warnings may be needed during the afternoon and early evening as scattered strong to severe thunderstorms potentially track over the waters. There may be a bit of a break in the winds tonight as the front slows down. Marginal Small Craft Advisories may be needed for portions of the waters Friday in northwest flow. Winds on Saturday will be out of the NW and near SCA criteria in the wake of a secondary cold front. Winds will likely taper off into Saturday evening as they gradually turn out of the south. Sub-advisory level winds are expected for Sunday before hazardous conditions return to the forecast on Monday. Increasing south to southwesterly winds may lead to Small Craft Advisories across the area waterways. Update as of: 253 AM EDT Thu Jun 18 2026
