Synopsis for the Gulf of America
1028 AM EDT Thu Mar 12 2026
.SYNOPSIS...A strong cold front extends from Apalachicola, Florida
southwestward to 26N92W and to inland Mexico just south of
Tampico. Fresh to strong N to NE winds and seas of 8 to 10 ft are
behind the front. N winds to near gale are over the far west-
central Gulf. The front will quickly reach from north-central
Florida to just SE of Veracruz, Mexico this afternoon, then
stall and significantly weaken over the southeastern Gulf tonight
into early Fri, dissipating Fri night. Marine conditions will
improve significantly early Fri through Sun as weak high pressure
settles just N of the basin. Another strong cold front is expected
to move into the NW Gulf Sun night and reach the southeastern
Gulf by Mon night. Strong to near gale-force winds will follow
the front along with seas rapidly becoming rough. Gale force
winds will be possible in the NW Gulf, and offshore Tamaulipas
and Veracruz, Mexico Mon and Mon night.
