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

Active Systems: 
The National Hurricane Center is issuing advisories on Hurricane 
Iona, located in the central Pacific basin well southeast of 
the Hawaiian Islands, and on Tropical Storm Keli also located 
in the central Pacific basin well east-southeast of the Hawaiian 
Islands.

1. Western East Pacific (EP98):
The area of low pressure located around 1500 miles east-southeast of 
the Hawaiian Islands has changed little since earlier today.  
Environmental conditions appear marginally conducive for some 
development of this system, and a tropical depression could form 
during the next day or two as it moves generally westward around 10 
mph and enters the Central Pacific basin around midweek. 
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...medium...60 percent.

2. South of Southwestern Mexico (EP99):
A large area of disorganized showers and thunderstorms located a few 
hundred miles south of the southern coast of Mexico is associated 
with a trough of low pressure.  Environmental conditions are 
expected to be conducive for development, and a tropical depression 
is likely to form during the next couple of days while the system 
moves west-northwestward around 15 mph, remaining well offshore of 
the southwestern coast of Mexico.   
* Formation chance through 48 hours...high...70 percent. 
* Formation chance through 7 days...high...90 percent.
