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

Moderate northeast winds and moderate seas are expected through the
weekend as multiple disturbances approach the area. Winds of 10-20
kt and seas 2-5 feet are anticipated through the weekend, and small
craft are urged to exercise caution. Numerous showers and
thunderstorms are also expected through this time and will cause
locally higher winds and waves. A second frontal boundary should
push through the coastal waters Monday, bringing rain chances to an
end along with a period of moderate to strong offshore flow.
