Synopsis for the Gulf of Mexico

.SYNOPSIS...Low pressure of 1014 mb is over the NW Gulf near
28N93W, with a trailing cold front to 23N94W and to inland
Mexico just north of Veracruz. Gale force northerly winds are
are behind the front south of 25N and W of 96W, while strong to
near gale force winds northerly winds are elsewhere behind the
front and low and elsewhere W of 90W. The low will gradually
weaken as it reaches to near 29N90W 1015 mb at about daybreak
this morning, with the cold front trailing from it to 26N92W and
to Veracruz. The low will track northeastward across the rest of
the north-central Gulf waters today and east-northeastward
across the NE Gulf tonight. The gale force northerly winds will
be confined to the SW Gulf offshore Veracruz by early this
afternoon, then diminish tonight. The front will exit the
southeastern Gulf Tue night and be over the Straits of Florida
Wed. High pressure will build over the NW Gulf in the wake of
the front, except a trough will persist over the far SW Gulf Tue
and Wed. This pattern will allow for winds to diminish and seas
to subside, except for fresh to strong northwest winds along the
Mexican coast west of the trough. Looking ahead, another cold
front will move into the northern Gulf Fri and reach from the NE
Gulf to the central and SW Gulf areas by late Fri.
