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

High pressure over the southeast gulf will keep a predominantly
westerly to SW flow regime through the remainder of the week. There
will be the usual diurnal increase in winds over the eastern waters
where winds approach and sometimes slightly exceed 15 knots during
the evening and part of the overnight hours before diminishing. A
weak front will settle toward the northern gulf Thursday and remain
nearby through the weekend, bringing increasing thunderstorm
coverage. Seas will generally remain 1 to 3 feet nearshore and 2 to
4 feet offshore, although locally hazardous winds, waves, lightning,
and reduced visibility will occur near stronger storms.
