Marine Forecast
Synopsis: Northerly breezes will freshen through the rest of this afternoon and evening, becoming strong. This will occur due to the interaction of a surface high pressure center over the western Gulf and a strengthening low center moving northeast past the Delmarva Peninsula. On Friday, breezes will ease and turn northeast, as the western Gulf surface high passes across north Florida. Easterly breezes will freshen on Saturday, as strong high pressure consolidates near North Carolina. It will move east into the Atlantic on Sunday and Monday, and a trailing ridge will settle down the Florida Peninsula, easing winds over Keys waters. The next cold front will arrive on Tuesday.
