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

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 today. 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 the afternoon hours 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 the
pressure gradient again tightens over the Gulf. Easterly winds will
increase back to near advisory levels in the offshore waters and
seas will increase to 4 to 6 feet.
