Synopsis for the Gulf of America

320 PM EDT Sat Jun 27 2026



.SYNOPSIS...The Atlantic ridge extends across Florida into the

Gulf region. This ridge will persist through the forecast period

supporting a gentle to moderate anticyclonic flow across the 

basin during this time, except for fresh to locally strong NE to E

winds pulsing off the northwestern Yucatan Peninsula nightly 

through Thu, and moderate to locally fresh SE to S winds across 

the northwestern Gulf through Sun night. Looking ahead, a weak 

frontal boundary will sink southward into the northeast Gulf Mon 

night into Tue and gradually dissipate.
