.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.
