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

High pressure centered over the area will gradually shift to the
east and southeast by Thursday and Friday. Winds will remain more
variable and near or below 10 knots while seas remain below 2 feet
today. 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 Friday night. Seas will respond and increase to 4 to 6 feet
in the open Gulf waters. After the front moves through on Sunday,
winds will shift to the northwest, but choppy conditions will
persist.
