Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Thu Jul 31 2025

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

Active Systems: 
The National Hurricane Center is issuing advisories on Tropical 
Storm Iona, located in the central Pacific basin well southwest of 
the Hawaiian Islands and recently-formed Tropical Storm Gil, 
located well south-southwest of the southern Baja California 
peninsula.

1. Well Southeast of the Hawaiian Islands (CP92):
Disorganized showers and thunderstorms associated with a broad area 
of low pressure located about 750 miles southeast of Hilo, Hawaii, 
continue to persist. Although the system lacks a well-defined 
low-level center at this time, some additional development is 
possible, and a short-lived tropical depression could still form 
during the next day or so. After that time, environmental conditions 
are expected to become less conducive for further development.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.

2. Central East Pacific:
An area of low pressure is expected to form well south of 
southwestern Mexico in the next couple of days. Environmental 
conditions appear conducive for some gradual development of this 
system, and a tropical depression is likely to form 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...high...70 percent.
