.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Weak low pressure will be developing along the Texas coast this
afternoon/evening 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.
