.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.
Although could meteorologically justify replacing SCY with SCS in
the tidal lakes right now, makes more sense from a messaging
perspective to keep SCY out during lull until nocturnal winds
increase there. Overall though, 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.
