Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
309 PM PDT Mon Apr 7 2025

.SYNOPSIS...winds in the Gulf of Papagayo region will become
fresh northeast to east winds on Wed, but pulse fresh to strong
mainly at night and into the early morning hours thereafter as
high pressure in the wake of a Gulf of America cold front builds
north of the region. Seas may build to rough with these winds
starting early Thu. Large NW swell will begin to impact the
outer waters of Guatemala Tue through Wed as a Tehuantepec gale
event develops, then again possibly Thu night into next weekend.
Elsewhere, mixed SW and NW swell will maintain moderate seas
between Ecuador and the Galapagos Islands through Tue night,
with new SW long-period swell expected to reach the Galapagos
Islands by Wed building seas to around 8 ft. Otherwise, gentle
to locally moderate winds are expected across the remainder of
the waters, along with slight to moderate seas, except moderate
to fresh winds in the Gulf of Panama Wed night.
