Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extending from South Florida
southwestward to 23N87W and to 20N95W will reach from the
Straits of Florida to the Yucatan Peninsula this evening before
weakening as it exits the basin. High pressure in the wake of
the front will slide eastward through late Tue as a low pressure
system develops over eastern Texas, and quickly tracks
northeastward across the southern U.S while deepening. The low
will drag a strong cold front across the Gulf of Mexico late Tue
afternoon through Thu. Near gale-force to gale-force southerly
winds are expected ahead of the front over the NW and north-
central Gulf Tue and Tue night, and gale-force northwest winds
are expected over the NW Gulf Tue into early Tue night.
Gale-force winds are expected offshore Veracruz Wed in the wake
of the front. Similar winds may occur in a small area just
northeast of Tampico early Wed. Winds and sea conditions will
gradually improve by Fri. Fresh southerly return flow will begin
to set-up in the far western Gulf starting Sat in response to
the next cold front that will be approaching the NW Gulf. Fresh
to strong east winds will surge from the southwestern Atlantic
through the Straits of Florida and into the far southeastern
Gulf Sat and Sat night.
