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

High pressure will slide to the east of the area over the next
36 hours, and we may need Small Craft Exercise Caution headlines by
very late Monday afternoon and Monday night over some of the outer
waters. A period of stronger winds, perhaps requiring Small Craft
Advisories, is expected beginning late Wednesday and continuing into
the weekend, especially over the open waters. Not out of the
question that we could see a few gusts to gale force Wednesday night
into Thanksgiving Day.
