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

Conditions will continue to improve tonight into tomorrow as a high
pressure system becomes centered over the region. Winds will turn
more easterly and then southeasterly at 5 to 10 knots and seas will
fall to 3 feet or less. These conditions will continue through
Saturday. The high will shift to the east Saturday night and Sunday
and southeast winds will increase to 10 to 15 knots by Sunday
morning. Further strengthening of the winds to 15 to 20 knots is
expected by Sunday afternoon as a low pressure system to the north
intensifies. A strong cold front will then pass through the waters
Sunday night into early Monday. Ahead of the front, southwest winds
will increase to 20 to 25 knots and seas will rise to 5 to 7 feet.
Behind the front, winds will shift to the northwest and increase to
30 to 35 knots with higher gusts. These gale conditions will push
seas over 10 feet in the Gulf waters creating very hazardous boating
conditions. The gale conditions will linger into Monday night before
gradually easing on Tuesday as another high pressure system becomes
more centered over the waters.
