Synopsis for the Gulf of America
412 PM EDT Fri Mar 13 2026
.SYNOPSIS...A weakening cold front extends from the Straits of
Florida to inland the NE Yucatan Peninsula. The front will stall
and lift back to the N as a warm front on Sat as high pressure
over the region begins to shift eastward. A strong cold front is
expected to move into the NW Gulf late Sun night, quickly reach
the southeastern Gulf by Mon night and slow down as it moves into
the northwestern Caribbean by late Tue. Strong to near gale-force
N winds will follow the front along with seas rapidly becoming
rough. Gale-force winds will be possible in the NW Gulf, and
offshore Tampico and Veracruz, Mexico on Sun night and Mon. The
winds offshore Veracruz may attain brief gusts to storm-force. In
the wake of the front, high pressure will build across the region
into midweek.
