 .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 today as a broad area of high
 pressure remains centered over the region. A rapid change in
 conditions will then take place tonight and Sunday morning as a very
 strong cold front moves through. Winds will turn northerly and
 increase in speed to between 25 and 30 knots with higher gusts from
 mid day Sunday through Monday morning. Small Craft Advisories and
 Gale Warnings are in effect for the waters over this time period.
 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.
