.Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote
Blanche Bays...
Low seas and moderate onshore winds will prevail to the end of the
work week as high pressure largely remains in charge. High
pressure will begin backing into central Texas late Thursday into
Friday, igniting a pressure gradient and increasing easterly
winds. This may result in a period of Small Craft Advisory
conditions and very likely will signal the return of some rain
chances over coastal waters.
