Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Thu Sep 18 2025

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

1. South of the Southern Tip of the Baja California Peninsula (EP96):
Showers and thunderstorms remain displaced well to the west of a 
broad area of low pressure located a few hundred miles south of the 
southern tip of the Baja California Peninsula. Although a tropical 
depression is still likely to form during the next day or so, the 
system is forecast to encounter progressively cooler waters and a 
drier, stable airmass over the weekend, which will inhibit any 
further development.
*Formation chance through 48 hours...high...70 percent.
*Formation chance through 7 days...high...70 percent.

2. Off the Coast of Southern Mexico:
A large area of disorganized showers and thunderstorms located a 
couple of hundred miles south of the southern coast of Mexico is 
associated with a trough of low pressure. Environmental conditions 
could support some gradual development of this system during the 
next several days while it moves generally west-northwestward at 5 
to 10 mph, roughly parallel to the coast of southern and 
southwestern Mexico.
*Formation chance through 48 hours...low...10 percent.
*Formation chance through 7 days...low...30 percent.
