Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
101 AM PDT Mon Oct 13 2025

.SYNOPSIS...A very moist and unstable atmospheric environment
will be favorable for showers and thunderstorms to continue to
develop over the regional waters. Looking ahead, broad low
pressure is developing offshore Guatemala. Little development is
expected over the next few days while the low remains nearly
stationary, but environmental conditions area likely to become
more conducive for tropical development of the low later in the
week. There is a medium chance that a tropical depression forms
while the system moves N or NW offshore Guatemala or southern
Mexico toward the end of the week or this weekend.
