Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Sun Jul 15 2018

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

1. Showers and thunderstorms in association with a low pressure system
located about 1200 miles east-southeast of the Big Island of Hawaii
are showing signs of organization.  Environmental conditions are
expected to be conducive for the development of a tropical
depression during the next day or so before upper-level winds
increase by mid-week. This system is moving westward and is expected
to cross into the Central Pacific basin on Monday.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...80 percent.

2. Shower and thunderstorm activity associated with a tropical wave
located several hundred miles south-southwest of the southern tip
of the Baja California Peninsula has changed little this evening.
However, recent satellite-derived wind data indicate that this
disturbance is producing gale-force wind gusts east of the wave
axis in the strongest thunderstorms.  Although the environment is
expected to be only marginally conducive, some additional
development is possible during the next day or so while the system
moves westward to west-northwestward over the open East Pacific. By
Wednesday, strong upper-level winds will likely prevent further
development.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
