Synopsis for the E Pacific within 250 nm of Mexico
144 AM PDT Fri Oct 17 2025

.SYNOPSIS...Moderate to locally fresh NW winds and locally
rough seas will prevail offshore of Baja California through this
morning. Moderate NW winds are forecast in the central and
southern Gulf of California Sat evening through Mon. Looking
ahead, a broad area of low pressure, EP91, is centered offshore
of southern Mexico. Environmental conditions appear conducive
for gradual development of this disturbance, and a tropical
depression could form during the next couple of days or so. The
system is forecast to move slowly west-northwestward or
northwestward near the coast of southern and southwestern Mexico
through the weekend. There is a medium chance of tropical
development within the next 48 hours. Regardless of development,
increasing winds and building seas are possible offshore of
southern Mexico through this weekend. Fresh to strong N gap winds
and locally rough seas are expected in the Gulf of Tehuantepec
Mon through late next week.
