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

Southeast winds of 5 to 10 knots will persist through this afternoon,
but a cold front will gradually shift winds to the north tonight into
tomorrow. By tomorrow night, these northerly winds will strengthen
to 15 to 25 knots and then linger into Monday. By Monday night, high
pressure moving over the waters will allow the winds to relax back
to 10 to 15 knots and also shift winds to the northeast and
eventually southeast. These southeast winds of 10 to 15 knots will
then remain in place into the middle of next week.
