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

A cold front moved into the coastal waters last night and surface
high pressure is quickly building in behind it. The pressure
gradient will tighten across the coastal waters as weak persistent
low pressure over the southeastern Gulf and large area of high
pressure to the north and northeast dominate the region over the
next few days. Winds have weakened a fair amount this morning in
response to slight weakening in the pressure gradient as a shortwave
moving southeastward through the parent upper level trough
approaches the base of this feature. Wind will begin to increase
once again this evening with strong northeast winds continuing
through Saturday morning as the base of the trough digs farther
southeast. Winds will generally be around 15 to 20 kts with frequent
gusts abv 20 kts. An Exercise Caution headline was added to fill the
gap between last night`s and tonight`s Small Craft Advisories. This
upcoming SCY will continue through Saturday morning for all of the
waters again. Winds will finally relax during the day Saturday as
high pressure builds in more.
