Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
833 AM PDT Sat Sep 21 2024

.SYNOPSIS...Moderate to fresh southwest to west winds south of
the monsoon trough will change little through the weekend, then
increase to fresh to near gale force speeds across the offshore
waters from Costa Rica to Guatemala late Mon through Wed night.
Seas will build during this time in mixed swell. The monsoonal
flow is expected to become very active, and dominate the region
through next week. This pattern will generate increasing westerly
wind waves moving into the area waters. Periods of very active
weather are also expected across the Central America offshore
waters through at least mid week.
