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

Light to moderate SW winds gradually shift west this evening as a
cold front approaches, followed by a northwest to north flow
tonight post-frontal passage. As winds becoming northerly tonight
they will also begin to ramp up, and a brief period of Small Craft
Advisory conditions are expected through early tomorrow. Tomorrow
afternoon into tomorrow night, light to moderate NE flow becomes E
and eventually SE as surface high pressure moves off to our east.
A steady light onshore flow will then prevail through the weekend
into next week. Cool shelf waters combined with warm moisture
return and mostly calm conditions will likely bring back the
occurrence of marine fog by the weekend through much of next week.
