.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Strong winds are developing in the wake of a cold front that moved
through the waters earlier this monring. These strong northerly
winds of 25 to 30 knots will produce frequent gusts of 30 to
35 knots over the waters. However, winds could gusts 35 to 40 knots
over the outer offshore waters resuling inte gale conditions. Small
Craft Advisories and Gale Warnings are already 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. These
lighter winds and calmer seas will persist through Thursday night. A
front will shift the winds to an offshore direction on Friday as a
weak front slides through, but winds will remain below any advisory
thresholds.
