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

.SYNOPSIS...Monsoonal winds, associated seas, and numerous
thunderstorms will dominate the region for the remainder of the
week. A broad area of low pressure could form late this week a
couple of hundred nautical miles off the coast of southern Mexico
or Guatemala. Some slow development is possible this weekend and
early next week while the system meanders near the coast. This
will allow for the monsoon trough to lift farther northward
toward the Gulf of Tehuantepec, with winds to the west of 88W
increasing to fresh to locally strong, leading to building seas
of 8 to 11 ft at times. Look for thunderstorm activity to also
increase during this time. Fresh to strong SW winds are expected
to develop west of Colombia Fri and shift into the Gulf of Panama
Fri night and Sat before diminishing. Seas may build to around 8
ft there with these winds.
