Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
813 PM PDT Sun Jun 22 2025

.SYNOPSIS...Fresh to locally strong NE to E winds will
develop across the Papagayo region tonight as low pressure
organizes to the southwest. Strong NE to E winds and locally
rough seas are expected to continue in this region and expand
westward into the waters offshore of El Salvador and Guatemala
Mon into midweek as this low pressure strengthens to the south of
this area. Environmental conditions appear conducive for
subsequent gradual development of this low, and a tropical
depression is likely to form by the middle of the week while the
system moves west-northwestward, and off the coasts of Central
America and southern Mexico. There is a low chance of tropical
formation within the next two days, and a high chance of
formation within the next seven days.
