Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
720 PM PDT Sun Oct 12 2025

.SYNOPSIS...SW swell will support combined seas to 7 ft off
northern Central America through Mon, before decaying slightly
for the remainder of the week.  A very moist and unstable
atmospheric environment will be favorable for showers and
thunderstorms to continue to develop over the regional waters.
Looking ahead, low pressure is likely to form south of Guatemala
by mid- week, and environmental conditions may be conducive for
some tropical development of this low as it moves slowly north or
northwest late this week, bringing fresh to occasionally strong
winds and moderate to rough seas off Guatemala and El Salvador
Thu and Fri.
