Tropical Weather Outlook
NWS Central Pacific Hurricane Center Honolulu HI
Issued by NWS National Hurricane Center Miami FL
200 AM HST Fri Jul 25 2025
For the central North Pacific...between 140W and 180W:
Well Southeast of the Hawaiian Islands:
An area of low pressure located well southeast of the Hawaiian
Islands is producing a large area of showers and thunderstorms.
Some gradual development of this system is possible, and a tropical
depression could form late this weekend or early next week as it
moves generally westward at 10 to 15 mph across the far western
portion of the eastern Pacific and into the Central Pacific basin.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...50 percent.
Could form in the EPAC first (in which case this system won't be named Iona) or could not form at all.
Now an invest (EP97) for it.

Edit:
Now CP90:
