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

Active Systems: 
The National Hurricane Center is issuing advisories on Tropical 
Storm Juliette, located in the eastern Pacific basin several hundred 
miles west of the southern tip of the Baja California peninsula.

1. Well South of the Hawaiian Islands:
A trough of low pressure located several hundred miles south of the 
Hawaiian Islands continues to produce disorganized showers and 
thunderstorms.  Environmental conditions are only marginally 
conducive for some slow development of this system over the next few 
days while it moves westward at around 15 mph across the central 
Pacific basin.  By Saturday, conditions are expected to become 
unfavorable for further development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

2. Well Southwest of the Baja California Peninsula:
A tropical wave located several hundred miles southwest of the coast 
of southwestern Mexico continues to produce a large area of 
disorganized showers and thunderstorms.  Environmental conditions 
appear favorable for gradual development of this system during the 
next few days, and a tropical depression is likely to form over the 
weekend while the system moves westward to west-northwestward at 
around 15 mph across the central to western part of the eastern 
Pacific basin.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...70 percent.

3. South of Southern Mexico:
Another area of low pressure could form this weekend offshore of the 
coast of southern Mexico.  Environmental conditions appear conducive 
for some gradual development of this system during the early and 
middle portions of next week while it moves generally 
west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.
