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



Active Systems:

The National Hurricane Center is issuing advisories on Hurricane 

Lala, located a few hundred miles southeast of Lisianski Island.



Central Pacific (EP90):

A broad area of low pressure located well to the east-southeast of 

the Hawaiian Islands is producing showers and thunderstorms that 

are gradually becoming better organized.  Environmental conditions 

appear favorable for further development of this system, and a 

tropical depression is likely to form during the next day or so 

while the disturbance moves westward to west-northwestward at 10 to 

15 mph and crosses into the Central Pacific tonight.  Interests in 

the Hawaiian Islands should closely monitor the progress of this 

system.

* Formation chance through 48 hours...high...90 percent.

* Formation chance through 7 days...high...90 percent.



South-Southwest of Mexico:

An area of low pressure is expected to form several hundred miles 

south-southwest of the coast of southern Mexico around the end of 

the week. Gradual development of this system is likely thereafter, 

and a tropical depression is likely to form this weekend  while the 

system moves generally west-northwestward, remaining well offshore 

of Mexico.

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 7 days...high...80 percent.
