1100 AM PDT Wed Jul 30 2025

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

Active Systems: 
The National Hurricane Center is issuing advisories on Hurricane 
Iona, located in the central Pacific basin well south of the 
Hawaiian Islands, and on Tropical Storm Keli also located in the 
central Pacific basin well south of the Hawaiian Islands.

1. Well East-Southeast of the Hawaiian Islands (CP92):
Showers and thunderstorms associated with an area of low pressure 
located around 1000 miles east-southeast of the Hawaiian Islands 
remain limited.  However, if persistent showers and thunderstorms 
re-develop during the next day or so, a short-lived tropical 
depression could still form.  After that time, environmental 
conditions are expected to become less conducive for development.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.

2. South of Southwestern Mexico (EP99):
Shower activity associated with a trough of low pressure located 
several hundred miles southwest of the southwestern coast of Mexico 
has become a little better organized since yesterday. Environmental 
conditions appear conducive for additional development, and a 
tropical depression is likely to form during the next day or two 
while the system moves west-northwestward around 15 mph, remaining 
well offshore of the southwestern coast of Mexico. 
* Formation chance through 48 hours...high...80 percent. 
* Formation chance through 7 days...high...90 percent.

3. Central East Pacific:
An area of low pressure is forecast to develop well south of 
southern or southwestern Mexico late this week.  Environmental 
conditions appear conducive for some gradual development of this 
system and a tropical depression could develop over the weekend or 
early next week as the system moves west-northwestward at 10 to 15 
mph.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 7 days...medium...60 percent.
