.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Continued gusty easterly winds of 15 to 20 knots will perist into
tonight over the waters resulting in continued rough seas. Small
craft advisories remain in effect through this evening due to these
conditions. Winds should gradually weaken and become more
southeasterly Tuesday as the pressure gradient relaxes ahead of the
approaching cold front. Given the expected flattening of the upper-
level trough aloft and limited support behind the frontal boundary,
a significant post-frontal wind surge does not appear likely. Winds
should shift offshore Wednesday into Thursday, generally remaining
light to moderate as surface high pressure builds into the region.
This will also allow seas to gradually subside. Showers will be
possible Tuesday night into Wednesday before drier conditions
return. Another round of showers will also move through the waters
Friday as a reinforcing cold front sweeps through the region.
