Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
359 AM CDT Tue Jun 27 2017

.SYNOPSIS...
Easterly winds today will shift more southeasterly tonight as high
pressure ridges westward along the Gulf coast. A disturbance aloft
and deep tropical moisture over the area will result in scattered
to numerous showers and thunderstorms the next few days. Winds
and seas will be locally higher near thunderstorms. By the
weekend, high pressure and drier air aloft is expected to limit
shower and thunderstorm activity, with a light to moderate onshore
flow continuing.
