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

Persistent north-northeast winds of 15 to 25 knots and rough seas
ranging from 3 to 5 feet in the tidal lakes and sounds to 5 to
8 feet in the open Gulf waters will be the rule through Saturday.
These conditions are in response to a low off the coast of Florida
and a high centered over the Southern Plains. These rough conditions
will keep a small craft advisory in place for all of the waters
through Saturday. Sunday will see the high over Texas become more
centered over the region. As this occurs, winds will quickly drop to
around 10 knots and turn more variable. These lighter winds and
gradually improving seas will persist through Monday. A weak front
will slip through the waters on Tuesday, and a more persistent
northerly wind of 10 to 15 knots will take hold behind the front for
both Tuesday and Wednesday. .
