1100 AM PDT Thu Oct 18 2018

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

1. An extensive area of disorganized showers and thunderstorms extends
from Central America westward to the south of the coast of Mexico
for several hundred miles.  A broad area of low pressure is
embedded within this region of disturbed weather near the Gulf of
Tehuantepec, but satellite images indicate that the system has lost
organization compared to the past couple of days.  Still,
environmental conditions appear conducive for development, and a
tropical depression or tropical storm is likely to form over the
weekend or early next week while the system moves generally
west-northwestward at 10 to 15 mph near or just offshore the coast
of southern Mexico.  Additional information on this system can be
found in High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

For additional information on the low near the Gulf of Tehuantepec

Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and
