1100 PM PDT Sat Jul 21 2018
For the eastern North Pacific...east of 140 degrees west longitude:
1. Disorganized showers and thunderstorms continue in association with
an area of low pressure located about 1250 miles east-southeast of
the Big Island of Hawaii. Development of this system is not
expected due to strong upper-level winds. The low is forecast to
move westward at 10 to 15 mph and cross into the Central Pacific
basin by Sunday night.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
2. A large area of disturbed weather is located several hundred miles
south of the southwestern coast of Mexico. Although this system
remains disorganized, environmental conditions are expected to
become somewhat conducive for development, and a tropical depression
could form by the middle part of next week. This disturbance is
expected to move toward the west or 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...50 percent.
3. An area of low pressure is forecast to form in a few days several
hundred miles south of the southern coast of Mexico. Environmental
conditions appear to be conducive for gradual development while the
system 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.
