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

Winds have finally eased some, back under 15kts, as we see high
pressure start trying to build in. 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.
