Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
802 PM PDT Tue Jun 11 2024

.SYNOPSIS...Monsoonal winds, associated seas, and scattered to
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.
