.Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote Blanche Bays...
Northerly flow shuts off late tonight and onshore winds resume by Friday morning. Breezy southwest winds will prevail on gradient between high to the east and developing weather system in the south Plains. This should help abate low water conditions somewhat for Friday, but water levels will still fall to around -1.0 feet. A series of strong cold fronts move into the northern Gulf on Friday and again Saturday. Strong, hazardous winds and seas will start as early as sunrise Saturday. A prolonged period of offshore winds will prevail to the end of the weekend exacerbating low water levels at low tide.
