Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
1227 PM PDT Wed Jun 12 2024

.SYNOPSIS...Monsoonal winds, associated seas, and numerous
thunderstorms will dominate the region through at least 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 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. Seas may
also build to 6 to 8 ft west of Ecuador late in the week into the
weekend in southerly swell.
