913 AM EDT Wed Sep 9 2026



.SYNOPSIS...Weak high pressure will persist through the weekend,

supporting mostly light to gentle winds and slight seas over much

of the waters. Winds will pulse to fresh with moderate seas off 

the western Yucatan Peninsula during the evenings due to a diurnal

surface trough moving westward from the peninsula each night.
