1100 PM PDT Wed Sep 17 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 off the 
coast of southwestern Mexico is producing a large area of showers 
and thunderstorms. Satellite-derived wind data indicate that the 
circulation remains fairly well organized. Environmental conditions 
are conducive for further development of this system, and a tropical 
depression is likely to form in the next day or two while it moves 
west-northwestward at 10 to 15 mph over the central portion of the 
eastern Pacific. However, the system is expected to encounter cooler 
waters and a drier airmass over the weekend, which will inhibit 
additional development.
*Formation chance through 48 hours...high...80 percent.
*Formation chance through 7 days...high...80 percent.
