TROPICAL WEATHER OUTLOOK...CORRECTED
NWS NATIONAL HURRICANE CENTER MIAMI FL
500 AM PDT MON AUG 24 2015

Corrected to change the category from medium to high for the
formation probability of the first system in the outlook

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

1. Satellite data overnight that the circulation of the slow-moving low
pressure area located about 1500 miles west-southwest of the
southern tip of the Baja California peninsula is gradually becoming
better defined. Shower and thunderstorm activity associated with
this system has also become better organized since yesterday.
Environmental conditions are expected to be conducive for continued
gradual development, and a tropical depression is likely to form
during the next day or two while the low begins to move slowly
northwestward.
* Formation chance through 48 hours...high...70 percent
* Formation chance through 5 days...high...80 percent

2. Disorganized shower activity located several hundred miles south of
the coast of southwestern Mexico are associated with a tropical
wave. Environmental conditions are expected to be conducive for
gradual development of this disturbance, and a tropical depression
is likely to form late this week while the system moves west-
northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...high...80 percent
