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

A cold and dry high pressure system will build over the waters
through Friday. As this colder and drier air moves across the warmer
waters, stronger winds aloft will transport down to the surface. As
a result, an extended period of small craft advisory conditons due
to northerly winds of 20 knots or greater and rough seas of over
7 feet will impact the waters through Friday. Winds will relax
slightly to between 15 and 20 knots and begin to turn more
southeasterly and southerly over the weekend as another low pressure
system pushes through the region.
