409 AM EDT Sun Jul 12 2026



.SYNOPSIS...A frontal boundary will remain N of the area through

midweek, enhancing thunderstorms across the northern Gulf waters.

Mariners can expect gusty winds, frequent lightning, and locally 

higher seas near the stronger thunderstorms. Elsewhere, high 

pressure will dominate, supporting gentle to moderate SE winds. 

Fresh to strong easterly winds will pulse offshore the Yucatan 

Peninsula each night.
