NWS NATIONAL HURRICANE CENTER MIAMI FL
1100 AM PDT WED SEP 21 2016

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

1. Shower and thunderstorm activity associated with a broad area of low
pressure located about 900 miles south-southwest of the southern tip
of the Baja California peninsula has not become any better organized
since this time yesterday.  However, environmental conditions are
expected to be conducive for gradual development, and a tropical
depression is likely to form later this week or this weekend.  This
system is forecast to move westward to west-northwestward at around
10 mph for the next couple of days and then turn northward by the
weekend.
* Formation chance through 48 hours...medium...40 percent
* Formation chance through 5 days...high...80 percent

2. Shower and thunderstorm activity has become a little more
concentrated this morning in association with a weak area of low
pressure located about 1350 miles east-southeast of the Big Island
of Hawaii.  Any additional development of this system is expected to
be slow to occur while it moves slowly westward during the next few
days.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...low...30 percent
