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

A reinforcing dry frontal passage will occur over the waters today
and a surface high will settle over the waters tonight into
tomorrow. Winds will be very light and variable through Saturday and
seas will run around 1 foot. Another front is projected to push
through on Sunday, and this front should be a bit stronger with some
cooler air associated with it. This will allow winds to rise to
10 to 15 knots on Monday, and there is some potential that winds
could rise higher into exercise caution range over the easter
waters. Seas will also respond and increase to 2 to 3 feet on
Monday.
