Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
121 AM PDT Wed Jun 12 2024

.SYNOPSIS...Monsoonal winds, associated seas, and numerous
thunderstorms will dominate the region this week. Low pressure is
expected to develop across portions of the Yucatan Peninsula,
the Bay of Campeche, and western portions of Central America Wed
and Thu. This will induce the monsoon trough to lift farther
northward toward the Gulf of Tehuantepec, with winds to the west
of 90W increasing to fresh to locally strong, leading to building
seas to 10 ft. Look for thunderstorm activity to also increase
during this time. Fresh to strong SW winds are expected to
develop south of Panama Fri and shift into the Gulf of Panama Fri
night and Sat.
