.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 to moderate east flow is possible through early Thursday
before the next cold front moves into the central Gulf. Winds will
veer south through the afternoon then turn quickly offshore and
strengthen Friday morning and a brief Small Craft Advisory may be
needed during daytime hours. A return to onshore flow occurs by late
Friday with warm moist air moving inland once again to the rest of
the period.
Cool shelf waters combined with warm moisture return and mostly calm
conditions will likely bring back the occurrence of marine fog by
the weekend.
