Disorganized showers and thunderstorms associated with a broad area 
of low pressure located about 650 miles southeast of Hilo, Hawaii, 
continue to persist. While the system currently lacks a 
well-defined low-level center, some development is possible during 
the next 24 hours. By this weekend, environmental conditions are 
expected to become less conducive for further development.

* Formation chance through 7 days...low...30 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...10 percent. 
* Formation chance through 7 days...high...70 percent.
