TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
500 PM PDT SUN OCT 18 2015

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

The National Hurricane Center is issuing advisories on Hurricane
Olaf, located about 1500 miles east-southeast of the Big Island
of Hawaii.

1. Showers and thunderstorms extending several hundred miles off the
coasts of southern Mexico and Guatemala are associated with a broad
area of low pressure, which is interacting with strong northerly
winds blowing over the Gulf of Tehuantepec.  Although some
development is possible during the next couple of days, a tropical
depression is more likely to form later this week once the low
begins to move west-northwestward and then northwestward away from
the Gulf of Tehuantepec.  Interests along the southern and
southwestern coasts of Mexico should monitor the progress of this
system during the next few days.  Regardless of development, heavy
rains are possible over portions of southern Mexico, Guatemala, and
El Salvador during the next couple of days.
* Formation chance through 48 hours...medium...40 percent
* Formation chance through 5 days...high...80 percent
