Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
300 PM PDT Sun Aug 11 2019

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

Special tropical weather outlook issued to update the discussion of
the low-pressure system south of the southern tip of the Baja
California peninsula.

1. Thunderstorm activity associated with a low pressure system located
a few hundred miles south of the southern tip of the Baja California
peninsula have become a little better organized during the past
several hours.  In addition, recent satellite-derived surface wind
data indicate that the low has become better defined, with winds
just below tropical-storm strength occurring near and to the east
of the center.  If this recent development trend continues, then
advisories could be initiated on a tropical depression or a tropical
storm later this evening while the disturbance moves westward to
west-northwestward, away from the coast of Mexico. Environmental
conditions are expected to become unfavorable for significant
development on Tuesday.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

2. A disturbance located a little less than 1000 miles southwest of the
Baja California peninsula is producing a large area of disorganized
showers and thunderstorms. Environmental conditions are expected to
become more conducive for tropical cyclone formation by the middle
of the week while the system moves west-northwestward at 10 to 15
mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
