Synopsis for the E Pacific within 250 nm of Mexico
900 AM PDT Sat Aug 23 2025

.SYNOPSIS...A tropical wave is producing disorganized showers
and thunderstorms several hundred miles south of the coast of
southwestern Mexico. Environmental conditions appear conducive
for development of this system, and a tropical depression is
likely to form by early next week while it moves generally west-
northwestward at 10 to 15 mph well off the coast of Mexico. There
is a medium chance of formation within the next 48 hours, and a
high chance within the next 7 days. Elsewhere, moderate to fresh
SE winds are expected periodically in the Gulf of California into
the middle of next week. Looking ahead, moderate to fresh N gap
winds will develop in the Gulf of Tehuantepec on Mon, with strong
winds and locally rough seas possible by midweek.
