Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
905 PM CST Sun Feb 18 2018

.SYNOPSIS...
Mainly southerly winds are expected during the period. These
winds will bring a warm moist air mass over relatively cooler
Gulf shelf waters with the result being dense sea fog through
Monday morning. Winds are expected to increase later tonight and
remain on the moderate and gusty side through Tuesday as the
pressure gradient across  the area tightens between a departing
surface high to the east and a developing surface low over the
Plains. A cold front will near the coastal waters late Wednesday
into Thursday. This front will bring a good chance for showers
and thunderstorms.
