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

An onshore flow pattern will be in place through much of next week.
Winds will also remain elevated through Sunday as a low pressure
system passes to the north of the waters. Seas will also increase to
up to 6 feet in the outer Gulf waters as a combination of wind waves
and swell creates hazardous boating conditions. However, the
protected sounds and lakes will see better conditions over the
weekend as winds and seas remain lower. Conditions will gradually
improve on Monday and Tuesday as winds fall below 15 knots.
