.Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote Blanche Bays...

Dense fog will be a concern, with dense fog advisories possible each day. Current guidance is not quite settled with spatial favoritism or duration. However, trends have been toward the Acadiana region and Vermilion Bay for tonight's highest confidence. Radiational fog looking less likely tonight, however, advection components are still favorable to develop areas of dense fog- mainly favoring lake, bays, and ship channels. Over the weekend, winds will increase with a small craft advisory possible.
