NWS National Hurricane Center Miami FL
500 AM PDT Fri Oct 19 2018

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

1. An area of low pressure centered a couple of hundred miles south of
Zihuatanejo, Mexico, has become a little better organized
overnight.  Environmental conditions are expected to become
increasingly favorable for further development, and a tropical
depression is likely to form during the next day or two while the
low moves westward or west-northwestward at 10 to 15 mph, offshore
of the coast of southwestern Mexico.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

2. Showers and thunderstorms associated with a low pressure system
centered less than 100 miles off the coast of Guatemala continue to
show signs of organization, and it is possible that a tropical
depression could be forming.  If this trend continues, then
advisories could be initiated on this system later today.  This
disturbance is forecast to move generally westward near the coast of
southern Mexico, and interests in that area should monitor the
progress of the low during the next several days.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.
