Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
904 AM PDT Fri Sep 20 2024

.SYNOPSIS...Moderate to fresh southwest to west winds south of
the monsoon trough will change little through Sun night, then
increase to fresh to strong speeds across the offshore waters
from Costa Rica to Guatemala Mon through Tue night. Seas will
build during this time in a mix of southwest swell and westerly
wind swell. The monsoonal flow is expected to become very active,
and dominate the region today into early 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 waters north of 06N through the weekend and possibly
into next week.
