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

Northerly offshore flow will persist today through early/mid-week
thanks to high pressure over the eastern US and a developing low off
the Carolina coast. This will keep conditions benign with light
waves/seas and winds, as well as dry conditions. East to east-
southeast flow does pick up some mid/late week, ranging 10 to
15 knots but will remain low impact and mainly dry into next
weekend.
