Synopsis for the Gulf of America
1056 PM EDT Fri Mar 28 2025
.SYNOPSIS...A 1031 mb high pressure located just W of Bermuda
extends a ridge westward across Florida into the Gulf waters.
The pressure gradient is tight enough to support fresh to strong E
to SE winds and moderate to rough seas across most of the basin.
Upper level low pressure along the Texas coast is triggering a
squall line across the NW Gulf this evening between 91W and 94W,
and will shift E and weaken tonight. The surface high pressure
will drift slowly eastward across the western Atlantic through the
weekend, allowing winds to diminish to moderate to fresh speeds
by Sat afternoon, with seas then subsiding below 8 ft by late Sat.
A cold front is forecast to enter the NW Gulf on Mon, and extend
from the Florida Big Bend to NE Mexico by Tue morning before
dissipating.
