.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

A cold front will continue to push through the coastal waters this
evening resulting in increasing offshore winds, with seas forecast
to increase in response. A Small Craft Advisory is in effect for
coastal waters generally this afternoon for zones west of the mouth
of the Mississippi River, to all areas overnight tonight through
Monday morning. High pressure builds into the region early in the
workweek, resulting in calmer conditions which will continue through
Thursday. Stronger winds and small craft advisory conditions are
expected to develop by the end of the week as a series of low
pressure systems passes north the waters.
