Synopsis for the Gulf of America

351 PM EDT Tue Sep 29 2026



.SYNOPSIS...A frontal trough extending from near Tampa Bay,

Florida to near Veracruz, Mexico supports scattered showers and

thunderstorms east of the axis mainly in the SE Gulf. This 

feature will gradually dissipate through the evening as high 

pressure builds in. Gentle to moderate return flow will prevail, 

except moderate to locally fresh over the western Gulf tonight. 

Winds will increase to moderate to locally fresh across the basin 

by Wed evening as the pressure gradient tightens. The gradient 

will weaken from west to east by the end of the week into the 

weekend as a front approaches the western portion, possibly moving

into the basin by the end of the weekend with weakening winds and

subsiding seas ahead of it. Increasing winds and building seas are

possibly behind the very slow moving front.
