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

High pressure centered over the area will gradually shift to the
east and southeast today and Friday. Winds will turn more east-
southeasterly and increase to 10 to 15 knots tonight 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 late in the weekend. Winds may briefly
get into the 15 to 20 knot range Friday night into Saturday, but do
not expect any prolonged periods where winds exceed 20 knots.

the front moves through late on Sunday, winds will shift to the
