.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

A cold front will move through the coastal waters this evening.
Tight pressure gradient currently in place with approaching cold
front is supporting borderline Small Craft Advisory conditions. A
progressive surface pattern will quickly result in weakening that
gradient Sunday, which will lend to subsiding winds and seas for the
first half of the upcoming week.
