miles west-northwest of the southern tip of the Baja California
peninsula.

Well South of the Hawaiian Islands:
A trough of low pressure located several hundred miles south of the
Hawaiian Islands continues to produce disorganized showers and
thunderstorms.  Environmental conditions are only marginally
conducive for some slow development of this system over the next
couple of days while it moves westward at around 15 mph across the
central Pacific basin.  By Saturday, conditions are expected to
become unfavorable for further development.

Well Southwest of the Baja California Peninsula:
A tropical wave located several hundred miles southwest of the coast
of southwestern Mexico continues to produce a large area of
disorganized showers and thunderstorms.  Environmental conditions
appear favorable for gradual development of this system during the
next few days, and a tropical depression is likely to form over the
weekend while the system moves westward to west-northwestward at
around 15 mph across the central to western part of the eastern
Pacific basin.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...80 percent.

South of Southern Mexico:
Another area of low pressure could form this weekend offshore of the
coast of southern Mexico.  Environmental conditions appear conducive
for some gradual development of this system late this weekend and
into early next week, and a tropical depression could form by
midweek as the system moves generally west-northwestward at 10 to 15
mph.
