For the eastern North Pacific...east of 140 degrees west longitude:

An elongated area of low pressure located about 1400 miles
southeast of The Big Island of Hawaii continues to become less
defined. The associated shower activity also remains limited,
and the chance for this system to become a tropical cyclone
development is decreasing. The disturbance is moving slowly
westward and could cross into the central Pacific basin later
* Formation chance through 48 hours...medium...30 percent
* formation chance through 5 days...medium...30 percent

Another broad and elongated area of low pressure located about 1500
miles west-southwest of the southern tip of Baja California is
moving west-northwestward at 10 to 15 mph. Although shower activity
remains disorganized, some slow development of this system could

disturbance is expected to move over cooler water and into a region
of less favorable upper-level winds, which should inhibit
* Formation chance through 48 hours...medium...50 percent
* formation chance through 5 days...medium...50 percent

An area of low pressure is expected to form several hundred
miles south of the coast of Mexico during the next few days.
Environmental conditions are expected to be conducive for
gradual development of the system after mid-week while it moves
west-northwestward to northwestward.
* Formation chance through 48 hours...low...near 0 percent
* formation chance through 5 days...low...30 percent
