Detailed Forecast


Synopsis: A weakening cold front will approach the local waters tonight and into Saturday. This will allow for a slight chance of showers across the Atlantic and Gulf waters on Saturday as it moves through. A stronger cold front will be moving through the local waters later on Sunday night and into Monday. This could increase the winds and seas behind the front. Therefore, hazardous marine conditions could develop across the Atlantic and Gulf waters during the early to middle portion of next week.
