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

High pressure centered over the area will gradually shift to the
east and southeast on Thursday and Friday. Winds will remain more
variable and below 10 knots while seas remain below 2 feet through
Wednesday. Winds will turn more east-southeasterly and increase to
10 to 15 knots on Thursday and Friday in response to the departing
high. Seas then also rise to 2 to 4 feet by Friday due to these
stronger winds. A frontal system is expected to slide through the
waters over the weekend, and this will further increase onshore
winds to 15 to 20 knots on Saturday. Seas will respond and increase
to 4 to 6 feet in the open Gulf waters. After the front moves
through on Sunday, these higher winds will shift to the northwest,
but choppy conditions will persist.
