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

1. Eastern portion of Central Pacific (CP90): 
Showers and thunderstorms have become slightly better organized in 
association with an area of low pressure located about 950 miles 
southeast of the Hawaiian Islands. Additional development of this 
system is expected as it moves generally westward staying well south 
of the Hawaiian Islands, and a short-lived tropical depression is 
likely to form during the next few days.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...high...70 percent.

2. Western East Pacific:
A trough of low pressure about 1500 miles east-southeast of the 
Hawaiian Islands is producing a large area of disorganized showers 
and thunderstorms. Some slow development of this system is possible 
as it moves generally westward during the next several days. 
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...30 percent.

3. South of Southwestern Mexico:
An area of low pressure is forecast to form well offshore of the 
southwestern coast of Mexico early next week. Thereafter, 
environmental conditions appear conducive for gradual development, 
and a tropical depression could form during the middle to latter 
part of next week as the system moves west-northwestward or 
northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.
