NWS National Hurricane Center Miami FL
1100 PM PDT Fri Oct 3 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Octave, located in the east Pacific, well to the 
west-southwest of the southern tip of the Baja California Peninsula.

1. Offshore of the Southwestern Coast of Mexico (EP99):
Showers and thunderstorms associated with a broad area of low 
pressure a few hundred miles off the southwestern coast of Mexico 
continue to become better organized this evening. However, recent 
satellite-derived wind data depict a circulation that remains 
somewhat broad, but if current trends persist, advisories on a 
tropical depression could be initiated on Saturday. The system is 
forecast to move very slowly west-northwestward, remaining offshore 
of the southwestern coast of Mexico during the next several days. 
Interests along the southwestern coast of Mexico should continue to 
monitor the progress of this system. For additional information, 
please see High Seas Forecasts issued by the National Weather 
Service.
* Formation chance through 48 hours...high...90 percent. 
* Formation chance through 7 days...high...90 percent.

2. South of Southern Mexico:
An area of low pressure is expected to form off the southern coast 
of Mexico by the middle of next week. Gradual development of this 
system is possible thereafter, and a tropical depression could form 
during the middle to latter part of next week while moving 
west-northwestward to northwestward, near or parallel to the coast 
of Mexico.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 7 days...medium...50 percent.
