1100 AM PDT Sat Jul 21 2018
For the eastern North Pacific...east of 140 degrees west longitude:
1. Showers and thunderstorms associated with an area of low pressure
located about 1700 miles west-southwest of the southern tip of the
Baja California peninsula have become a little better organized
since yesterday. However, the system is already embedded within
unfavorable upper-level winds and additional development appears
unlikely. The low is expected to move westward at 15 to 20 mph and
cross into the Central Pacific basin on late Sunday or early Monday.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.
2. Another area of disturbed weather is located several hundred miles
south of the southwest coast of Mexico. Although there are no signs
of organization at this time, conditions are forecast to become more
conducive for development and a tropical depression could form early
next week. This disturbance is expected to move toward the
west-northwest at 15 to 20 mph during the next several days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...60 percent.
3. And yet another area of low pressure is likely to form early next
week several hundred miles south of the southern coast of Mexico.
Environmental conditions appear to be conducive for gradual
development of this system while it moves toward the west or
west-northwest well south of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.
