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

A broad area of low pressure over the central Gulf and a high
pressure system over the eastern seaboard will keep a persistent
easterly flow of 15 to 25 knots in place across all of the waters
through tomorrow. These winds will also have a pretty long fetch
across the eastern Gulf waters, and this will support higher seas of
up to 10 feet in the open Gulf waters due to a combination of wind
waves and swell. Small craft advisories are in effect through Sunday
evening due to these hazardous conditions. The high will start to
become more dominant over the waters on Monday and Tuesday, and this
will allow the easterly winds to relax a bit to between 10 and
15 knots. Seas will also decrease to 2 to 4 feet as the winds relax.
This brief respite in rougher conditions will end on Wednesday and
Thursday as another low pressure system moves through the Gulf.
Easterly winds will increase back to near advisory levels in the
offshore waters and seas will increase to 4 to 6 feet.
