.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Surface high pressure will generally remain east of the local area
through early week. This will keep flow oriented onshore and fairly
light through mid week. Late week, the pressure gradient will
tighten as a surface low develops over West Texas and moves through
the southern portion of the Central Plains. Onshore winds will
strengthen in response to this. Guidance suggests winds of around
15- 20 knots in open Gulf waters Thursday and Friday which would
subsequently bring seas to 3-6 feet. Model consistency has not been
the greatest with this late week system, but regardless an increase
in flow seems likely.
