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 south-southeast of 
the Hawaiian Islands, and on Tropical Storm Keli also located in the 
central Pacific basin well southeast of the Hawaiian Islands. 

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 or 
tropical storm 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.

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 appear 
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.

Central East Pacific:
An area of low pressure is forecast to develop over the central East 
Pacific, several hundred miles south of the southern tip of the Baja 
California peninsula, late this week. Environmental conditions 
appear conducive for some gradual development of this system as it 
moves westward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 7 days...low...20 percent.
