Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
912 AM PDT Thu Jun 13 2024

.SYNOPSIS...Monsoonal winds, associated seas, and numerous
thunderstorms will dominate the region through the end of the
week. A broad area of low pressure could form Fri 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 even farther northward
toward the Gulf of Tehuantepec, with winds to the west of 90W
increasing to fresh to strong, leading to building seas of 8 to
12 ft at times, highest late weekend into early next week.
Meanwhile, 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 are likely build to around 8 ft
there with these winds.
