Synopsis for the Gulf of America

425 AM EDT Fri Jul 31 2026



.SYNOPSIS...A surface ridge will remain in control of the

weather pattern across the Gulf region promoting gentle to

moderate winds for the next several days. The exception will be

fresh NE winds off the northwest coast of the Yucatan peninsula

nightly into the weekend. Scattered showers and thunderstorms

will continue over the NE Gulf through the weekend as a frontal

boundary remains just N of the area, and a very moist and

unstable airmass prevails over region.
