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

High pressure has moved in but will continue to sliding east quickly
leading to light return flow by midday/early afternoon today. Weak
low pressure will begin to develop along the Texas coast tonight and
slowly drift east-northeast Thursday along the coast. This will
tighten the pressure gradient especially east of the Mississippi
River delta. Winds will increase with moderate to strong east-
southeast to easterly winds. This will have multiple impacts with
Small Craft Advisory conditions expected Thursday into Friday but
the increase in onshore winds will combine with the increasing tidal
cycle at the end of the week likely leading to at least some minor
coastal flooding. Main concern will be east facing shores of
Orleans, St Bernard, Plaquemines, and far southeastern St Tammany.
In addition coastal Hancock around Waveland will also deal with some
minor coastal flooding Thursday night through Friday morning. Winds
will relax and return to offshore late Friday and Friday night but
another weak surface low will develop Saturday moving across the
coastal waters late Saturday bringing another brief period of
moderate to strong winds.
