.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Winds will remain between 15 and 20 knots through later this morning
in the wake of a reinforcing front that pushed through the waters
yesterday. Afterwards this afternoon, winds will turn onshore at
10 to 15 knots as a high shifts to the east and a low pressure
system approaches from the west. These lighter onshore winds will
persist through Thursday night. Friday will see winds turn more east
and northeasterly behind the departing low. Saturday should see
winds increase further to at least exercise caution and possibly
small craft advisory range as a reinforcing front passes through the
waters and a colder airmass begins to move in from the north. By
Saturday night and Sunday, winds will increase further and a period
of 20 to 25 knot winds, rough seas, and small craft advisory
conditions will be in place through Monday.
