Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Elida, located several hundred miles west-southwest of the 
southern tip of the Baja California Peninsula.

Well Southwest of the Hawaiian Islands (CP90):
A broad area of low pressure located a few hundred miles southeast 
of Johnston Atoll is producing disorganized showers and 
thunderstorms away from the center. Development of this system, if 
any, is expected to be slow to occur while it moves westward at 
about 10 mph during the next day or so.  Environmental conditions 
are expected to become unfavorable for further development by this 
weekend.
* Formation chance through 48 hours...low...10 percent. 
* Formation chance through 7 days...low...10 percent.

Central and Western East Pacific:
A tropical wave located several hundred miles south-southwest of 
the coast of southwestern Mexico is producing a large area of 
disorganized showers and thunderstorms. Environmental conditions 
appear conducive for development of this system, and a tropical 
depression is expected to form over the weekend while it moves 
west-northwestward to northwestward at 10 to 15 mph over the central 
portion of the eastern Pacific.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high..90 percent.

Eastern and Central East Pacific:
A broad area of low pressure is forecast to develop well to the 
south of Mexico during the middle to the end of next week. 
Environmental conditions could support some gradual development of 
this system thereafter while it moves westward to west-northwestward 
across eastern and central portions of the eastern Pacific.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 7 days...low...20 percent.
