Synopsis for the Gulf of America

1017 AM EDT Mon Oct 5 2026



.SYNOPSIS...Fresh to locally strong N winds will follow a trough

along the E Mexican offshores through Tue. Weak surface ridging

over the NE Gulf will slowly shift eastward through late Tue 

ahead of a front stalling over the northern Gulf today through Wed

before it starts to weaken Wed night. Fresh NE to E winds and 

building seas are forecast N of the front. Looking ahead, gradual 

development of a trough in the southwestern Gulf is becoming 

more likely, and a a tropical depression is likely to form during

the middle or latter portion of the week. This system is expected

to drift eastward over the next few days, before it turns 

northward. Regardless of development, fresh to locally strong 

winds and rough seas are forecast over portions of Gulf Wed 

through Sat night.
