Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
833 AM PDT Sat May 30 2026

.SYNOPSIS...A weak pressure pattern across the region will
result in light to gentle winds through the period, with 
nocturnal pulses of moderate to fresh gap winds across the 
Papagayo region. Large SW swell will maintain rough seas across 
the southern waters, including between the Galapagos Islands and
Colombia through Sun before subsiding. Otherwise, moderate seas 
in SW swell will prevail across the forecast waters into the 
middle of next week. Expect convection to remain active across 
the area waters during the weekend.
