Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Fri Jul 20 2018
For the eastern North Pacific...east of 140 degrees west longitude:
1. An elongated area of low pressure located about 1500 miles southwest
of the southern tip of the Baja California peninsula is producing
disorganized cloudiness and showers. Some slow development of this
system is possible during the next couple of days before upper-level
winds become too strong for development. This system is expected to
move westward at 15 to 20 mph and cross into the Central Pacific
basin late this weekend.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.
2. A tropical wave located several hundred miles southwest of
Acapulco, Mexico, continues to produce a large area of disorganized
showers and thunderstorms. Gradual development of this system is
likely, and a tropical depression could form early next week while
the system moves westward to west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...60 percent.
3. An area of low pressure is likely to form early next week several
hundred miles south of the southern coast of Mexico. Environmental
conditions then appear to be conducive for gradual development of
this system while it moves westward or west-northwestward well south
of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.
