Synopsis for the Gulf of America
452 AM EDT Tue May 20 2025
.SYNOPSIS...Weak high pressure located just E of the Bahamas extends
a ridge W-NW across the NE Gulf. The pressure gradient between
this high pressure and lower pressure in Texas and in eastern
Mexico will maintain moderate to fresh SE winds and moderate seas
across the western Gulf through Tue. A weak cold front will move
into the N Gulf Tue night, stall, then lift north and dissipate
Wed night. Yet another weak front will sink into the NE Gulf Thu
through Thu night then dissipate. High pressure is expected to
move into the NE Gulf this coming weekend and dominate the basin.
E winds will pulse fresh to strong along and just north of the
Yucatan Peninsula each afternoon and evening through the period as
a trough develops daily and drifts westward at night. Smoke from
agricultural fires in southeastern Mexico will continue to
maintain hazy sky conditions across the W and SW Gulf through the
period.
