Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
853 AM PDT Sun Jun 15 2025

.SYNOPSIS...Large S to SW swell dominating the regional waters
will slowly subside through early next week. Tropical Storm
Dalila located SW of Cabo Corrientes, Mexico will continue to
weaken and turn more W tonight through Tue, moving away from the
coast. Low pressure offshore NW Costa Rica is expected to drift W
to W-NW through the middle of next week. Environmental
conditions appear conducive for gradual development of the low,
and a tropical depression could form by the middle of next week
while moving westward to west-northwestward just offshore of the
coasts of El Salvador, Guatemala, and southeastern Mexico.
Showers and thunderstorms are expected to remain active across
the regional waters in association with this system. This system
is being monitored for potential tropical development.
