.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 30 knots with higher gusts
from mid day Sunday 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.
