TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
500 AM PDT MON OCT 19 2015

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

The National Hurricane Center is issuing advisories on Hurricane
Olaf, located about 1400 miles east-southeast of the Big Island of
Hawaii.

1. Cloudiness and thunderstorms extending from near the coast of
Guatemala westward to along the south coast of Mexico are associated
with an area of low pressure located a few hundred miles south of
the Gulf of Tehuantepec.  The low is interacting with strong
northerly winds blowing through the Isthmus of Tehuantepec and into
the eastern Pacific, which could temporarily be impeding tropical
cyclone formation. Although some development of this system is still
possible during the next day or so, a tropical depression is more
likely to form around mid-week once the low begins to move
west-northwestward or northwestward away from this region. Interests
along the south-central and southwestern coasts of Mexico should
monitor the progress of this disturbance during the next few days.
Regardless of development, locally 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...50 percent
* Formation chance through 5 days...high...80 percent
