Synopsis for the Gulf of America

416 AM EDT Sun Jul 19 2026



.SYNOPSIS...A broad area of low pressure over the eastern Gulf

near 28N85.5W is gradually becoming better organized. This system

is expected to move slowly north to northwestward over the next 

couple of days, and could become a tropical depression. 

Regardless, this system will bring thunderstorms with heavy 

rainfall and strong gusty winds to the NE Gulf and adjacent 

portions of the Gulf coast through at least Tue. Away from this 

system, weak high pressure will dominate, producing gentle to 

moderate winds and slight to moderate seas through the period.
