Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
1009 AM CDT Mon Jun 18 2018

.SYNOPSIS...
A weak tropical wave will continue to move across the western
Gulf of Mexico and into Texas through tonight. This system will
interact with a surface high building in from the western
Atlantic and tighten the pressure gradient over the northwest
Gulf. The  result will be strong onshore flow and rough seas with
small craft conditions into this evening. Tides will also run
about a foot  above astronomical levels through this morning. The
tropical wave will also bring an increase in moisture with
numerous showers and storms through early in the week.
