Synopsis for the Gulf of America

.SYNOPSIS...A weak pressure gradient will generally maintain
gentle to moderate southeast to south winds across the basin,
except for light to gentle variable winds over the NE Gulf
through Fri. Moderate seas will be over the western Gulf while
mostly slight seas will be elsewhere through Fri. A diurnal
trough will pulse fresh to strong winds off the Yucatan
Peninsula during the evenings and at night through Fri. A strong
late-season cold front will emerge off the Texas coast Fri
night. The front will reach from northern Florida to the Bay of
Campeche by late Sat, then from central Florida to the Yucatan
peninsula on Sun before stalling over the southeastern Gulf Mon.
The front will be followed by fresh to strong north to northeast
winds, with winds reaching gale-force offshore Tampico and
Veracruz on Sat, lasting to into Sat night offshore Veracruz.
Seas are forecast to build to around 12 ft, but possibly higher
over waters affected by the gale conditions before subsiding Sun
and Sun night. Scattered showers and thunderstorms, some
possibly strong, are expected to precede the front. Mariners are
advised to keep up with the latest forecasts.
