Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
900 PM PDT Sun Oct 5 2025

.SYNOPSIS...Little change is expected in the weather pattern
across most of the region this week under a weak pressure
gradient. Gentle to moderate southerly winds are expected south
of the monsoon trough while light to gentle winds will prevail
to the N of it. Southerly swell will continue to propagate
across the region, bringing moderate seas in the 5 to 7 ft
range. Looking ahead, winds may increase to fresh speeds across
the offshore waters of Guatemala and El Salvador by the middle
of the week as a low pressure develops along the monsoon trough
before shifting westward into the Tehuantepec region.
