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

A cold and dry high pressure system will shift eastward across the
waters through Friday. As this cold and dry air moves across the
warmer waters, stronger winds aloft will continue to 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. A weak front will
slide offshore and stall over the waters early next week. Winds will
shift back to an offshore direction after the front moves through.
At the same time, a low pressure system will strengthen over the
northern Gulf Monday night into Tuesday. Northerly winds will
increase back into small craft advisory range as this low
strengthens over the waters.
