.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
The backdoor cold front is currently moving through the region and
was almost bisecting the region shortly after midnight. The front
will continues its slow march towards the coast moving off the MS
coast before the latest forecast is out. It will then slide off the
SELA coast just before sunrise. A very brief period of offshore
winds will occur immediately behind the front...brief. By mid late
morning winds will quickly veer to easterly over MS Sound along with
the Sounds and waters east of the Mississippi River Delta and
rapidly increase to Small Craft Advisory conditions. The winds will
finally start to shift more easterly south of the LA coast late
today and increase to Small Craft Advisory conditions late this
afternoon or this evening. The winds are responding to 2 features, a
large area of high pressure which will work down the Appalachians
and into the southeastern US while a weak tropical wave continues to
move northeast across the central Gulf and towards the LA coast by
the end of the week. These two features will keep a tight pressure
gradient in place leading to strong easterly and eventually
southeasterly winds into the weekend. This will lead to prolonged
hazardous marine conditions along with coastal flooding concerns,
especially along the coast east of the Mississippi River delta.
