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

Ridging will be in control through the weekend with onshore winds
and low seas expected.

The upper level pattern becomes active starting next Monday when a
series of waves are expected to move across northern Gulf states.
This will likely bring about periods of disturbed weather and
elevated winds and seas next week.
