.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 modest winds from the northeast today as weak surface high
pressure ridging across the Gulf coast states will build into the
coastal waters. The offshore winds along with seas will increase by
Thursday as a cold front moves into the coastal waters with the
potential for a small craft advisory for a portion of the coastal
waters. Offshore winds will remain elevated through Friday before
decreasing over the weekend as surface high pressure settles over
the region.
