 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
 
 Light onshore winds of 10 knots or less and calm seas of 2 feet or
 less will persist over the waters through Saturday as a broad area
 of high pressure remains centered over the region. A rapid change in
 conditions will then take place Saturday night and Sunday morning as
 a very strong cold front moves through. Winds will turn northerly
 and increase in speed to between 25 and 35 knots with higher gusts
 from Sunday afternoon through Monday morning. There is a decent
 probability that headlines will be issued for the waters over this
 time period due to high winds and rough seas anticipated. Another
 high will then quickly settle over the area on Tuesday, and this
 will allow winds to turn more easterly and fall back to less than
 10 knots. Seas will also begin to subside as the winds decrease
 Monday night into Tuesday.
