Synopsis for the Gulf of America

434 PM EDT Sun Sep 27 2026



.SYNOPSIS...Light to gentle winds and slight to moderate seas

will prevail through today, then become gentle to moderate SE

winds across the basin through the early part of the week as

high pressure builds over the southeast U.S. Looking ahead,

expect moderate to fresh winds and building seas over mostly the

western Gulf starting mid week, as the high pressure shifts

eastward ahead of a cold front moving through the Southern

Plains and approaching the northwest Gulf by late Fri.
