Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
808 AM PST Sun Dec 10 2023

.SYNOPSIS...The pressure gradient between higher pressure over
the NW Caribbean and the monsoon trough to the south will
continue forcing fresh to strong NE to E winds across the
Papagayo region through the next several days. Gentle to moderate
breezes are expected elsewhere. Otherwise, storm-force gap winds
north of the area over the Gulf of Tehuantepec will generate
large NW swell that will affect the Guatemala and El Salvador
