Synopsis for pascagoula to atchafalaya river out 60 nm -
surface high pressure centered across the northern gulf will maintain benign marine conditions today, with winds generally around 5 to 10 knots and seas of 2 feet or less. The ridge will gradually shift southward this weekend, establishing a predominantly westerly flow regime from Sunday through the middle of next week.
a typical summertime diurnal wind cycle is expected, with nocturnal winds increasing to around 10 to 15 knots during the overnight periods and early morning hours before relaxing closer to 5 to 10 knots during the daytimes. Seas will generally respond similarly, with 2 to 4 feet possible over the outer waters overnight and 1 to 2 feet during the day. Conditions should remain below headline criteria, although occasional gusts approaching 15-20 knots may occur over the outer waters during the stronger nocturnal wind periods and require an exercise caution headline. Strong subsidence aloft from upper level ridge influence will keep Thunderstorm coverage very limited during all but maybe the end of the forecast period.
