.MARINE... Southerly winds strengthen by this afternoon in the wake of the warm front. Advisories have been issued from 11 AM to 11 PM for all waters, and lingering for the mid bay through the night. Strong to severe storms are possible this afternoon and evening as well, which may prompt Special Marine Warnings. Leftover storms on Sunday would probably be limited to areas around southern MD, but trends suggest they will form farther to the south. Otherwise winds become northerly in the front's wake, and could result in marginal advisory conditions. Expect sub-SCA level conditions Sunday night into Monday as high pressure builds to the north. Southerly channeling may increase winds by Monday night. SCA conditions due to southerly channeling could occur Tuesday into Wednesday as a storm system and two possible cold fronts push across the region. Winds southeast 10 to 15 knots Tuesday. Winds south 10 to 20 knots gusts higher Wednesday. Update as of: 256 PM EDT Sat Jul 18 2026
