Synopsis for the Gulf of America

1017 PM EDT Thu Oct 1 2026



.SYNOPSIS...An upper-level low currently over SE Mexico will 

promote scattered showers and isolated thunderstorms over the E 

Gulf tonight, spreading to the N Gulf on Fri and Sat. A tightening

pressure gradient will increase SE winds up to fresh to locally 

strong over the E and central Gulf tonight and Fri. A weak cold 

moving across Texas will weaken the pressure gradient, allowing 

the winds across the Gulf to diminish Fri into the weekend. On 

Sun, the front will reach the NW Gulf, extending from Alabama to 

just offshore the Texas-Mexico border to near Veracruz on Mon 

morning. Winds behind the front should only be N to NE moderate to

locally fresh.
