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

Winds continue to be progged to prevail from the east through the
period as high pressure continues ridging into the northwest Gulf.
Periods of enhanced easterly flow and seas will develop over outer
20 to 60 nm waters as the gradient tightens with the passage of
waves.

Dry air and high pressure will keep precipitation chances to a
minimum.
