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

.SYNOPSIS...Monsoonal winds, associated seas, and numerous
thunderstorms will dominate the region into the weekend. 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 even farther northward
toward the Gulf of Tehuantepec, with winds to the west of 90W
increasing to fresh to locally 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 may build to around 8 ft there
with these winds.
