1100 AM PDT Thu Sep 18 2025

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

1. Off the Coast of Southwestern Mexico (EP96):
A broad area of low pressure located a few hundred miles southwest 
of the coast of southwestern Mexico is producing a large area of 
showers and thunderstorms to the west of the surface center.  
Although a tropical depression is likely to form during the next 
day or two, the system is forecast to encounter progressively 
cooler oceanic surface temperatures and a drier, stable airmass 
over the weekend, which should inhibit any additional development.
*Formation chance through 48 hours...high...80 percent.
*Formation chance through 7 days...high...80 percent.
