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

Winds across the coastal waters will remain elevated through mid day
Monday as high pressure continues to build into the area. The
gradient will begin to relax Monday afternoon with winds and waves
responding accordingly. Additional periods of moderate easterly
winds will be possible through the week. An inverted trough moving
through the northern Gulf will result in unsettled weather with
numerous showers and thunderstorms on Tuesday. The unsettled weather
will continue into Wednesday, though showers and storms will become
more scattered. Beyond Wednesday the pattern should become more
benign with only isolated showers and storms mainly across the outer
waters.
