Synopsis for the Gulf of Mexico
403 PM EDT Thu Mar 21 2024

.SYNOPSIS...A developing low pressure system near the coast of Texas
is forecast to track northeastward from the NW Gulf of Mexico to
inland southeastern U.S. Fri night and Sat. The trailing cold
front will reach from SW Louisiana to near Tampico, Mexico Fri
morning, from the Florida Panhandle to near Veracruz, Mexico Sat
morning, and exit the basin late Sat afternoon. Strong to near
gale-force southerly winds are forecast ahead of the front, with
fresh to strong northerly winds behind it. Widespread showers and
strong thunderstorms, some potentially severe, are expected with
the low center and the cold front. Mariners should monitor these
hazardous marine conditions and plan their routes accordingly.
High pressure in the wake of the front will quickly shift eastward
from late Sat night through Sun night, allowing for fresh to
strong southerly winds to develop over the western Gulf. These
winds will shift to the central and eastern Gulf Mon and Mon
night as a cold front moves across the western Gulf.
