Southwesterly winds will gradually increase through Sunday ahead of a strong cold front that will be entering the southeastern U.S. Isolated showers and thunderstorms will be possible ahead of this afternoon and evening. This strong front will cross our local waters during the overnight hours on Sunday night, with Small Craft Advisory conditions overspreading our local waters during the evening hours as westerly winds strengthen and then shift to northwesterly after midnight. Strong high pressure building into the southeastern states on Monday will result in occasional Gale Force wind gusts on Monday night, when Gale Warnings may be necessary. High pressure will shift eastward and will become centered directly over our local waters by midweek, allowing for winds and seas to gradually diminish. .GULF STREAM...
