Synopsis for the Gulf of Mexico
603 PM EDT Sat Apr 20 2024

.SYNOPSIS...High pressure extending across the basin from the
western Atlantic will begin to shift eastward tonight as a
rather weak cold front approaches the NW Gulf coast. Winds will
generally remain at gentle to moderate speeds throughout tonight
into early Sun. Winds will pulse fresh to strong in the evenings
NW of the Yucatan Peninsula through at least this evening. A cold
front is forecast to move into the NW Gulf late tonight into
early Sun, then reach the southeastern Gulf Monday and Monday
evening as it weakens. Fresh to locally strong winds and
building seas may follow the front through Sun night. High
pressure will again settle over the region by Tue and change
little through Thu night. The pressure gradient between the high
pressure and lower pressure over the southern Plains is expected
to increase the southeast winds in the western Gulf starting on
Thu.
