Synopsis for the Gulf of America

345 PM EDT Tue May 20 2025



.SYNOPSIS...A ridge extending from SW Florida to near Houston 

Texas combined with lower pressures over central Texas and Mexico 

will maintain moderate winds across the basin ahead of a cold

front. The weak cold front will move into the northern Gulf 

tonight, stall, then lift north and dissipate through Wed night. 

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. Winds may

freshen in the western Gulf starting Sat night. E winds will 

pulse fresh to locally 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 western Gulf through the 

period.
