Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
902 AM PDT Thu Oct 8 2026

.SYNOPSIS...Long-period southerly swell will produce moderate to
locally rough seas between Ecuador and the Galapagos Islands 
through tonight. Elsewhere, a weak high pressure north of the 
Caribbean will support moderate or lighter winds and moderate 
seas across much of the forecast waters through at the middle of 
next week. Looking ahead, an area of low pressure is forecast to 
form south of the coast of Guatemala early next week. Environmental
conditions appear conducive for some gradual development of this
system thereafter, and a tropical depression could form as it 
moves generally west-northwestward at around 10 kt. This system 
has a medium chance of tropical cyclone formation in the next 7 
days.
