Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
318 PM CST Tue Feb 20 2018

.SYNOPSIS...
A front will stall north of the coastal waters late Wednesday.
Therefore, an elevated southerly flow will persist through the end

Gulf shelf water, there will be the potential for sea fog through
Thursday morning over the near shore waters. This front will also
bring a good chance for showers and a few thunderstorms.
