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

A light onshore flow will prevail through the weekend, keeping a daily risk of sea fog in the forecast. Due to ongoing dense marine fog and elevated probabilities of fog persisting, the DF.Y was extended into tomorrow at noon for the nearshore marine zones. Brief periods of increased visibilities will be possible for all marine zones in the afternoon, however.

A strong offshore flow is expected in the wake of a cold front forecast to push through the coastal waters late Sunday night into early Monday. This will assist with clearing the fog, however with elevated offshore flow and gusts predicted, a SC.Y may become necessary.
