TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
500 AM PDT THU OCT 20 2016

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

1. Showers and thunderstorms have increased near a small area of low
pressure located about 700 miles south-southwest of the southern tip
of the Baja California peninsula.  Although upper-level winds are
only marginally conducive, this system has the potential to become a
tropical depression over the next couple of days before upper-level
winds become unfavorable for development.  The low is expected to
drift northward over the next several days.
* Formation chance through 48 hours...medium...40 percent
* Formation chance through 5 days...medium...40 percent

2. Disorganized cloudiness and showers over the far eastern Pacific
near the coast of Central America are associated with a surface
trough.  Environmental conditions are forecast to become more
favorable for some development of this disturbance over the
weekend while the system moves toward the west-northwest at
about 10 to 15 mph.  Regardless of development, locally heavy
rainfall is possible over portions of Central America during
the next couple of days.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...medium...40 percent
