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

1. A broad area of low pressure located south of the Guatemala-Mexico
border is producing disorganized cloudiness and shower activity.
Any development of this system is expected to be limited while it
drifts northwestward during the next few days due to possible
interaction with land and its proximity to a developing disturbance
located to its west.  Regardless of tropical cyclone development,
this system could produce heavy rainfall over portions of El
Salvador, southern Guatemala, and southeastern Mexico during the
next few days.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...low...20 percent

2. A low pressure system is expected to form during the next day or two
near a large area of disorganized showers and thunderstorms located
several hundred miles southwest of the Gulf of Tehuantepec.
This low is likely to develop into a tropical depression by early
next week and move northward or northeastward toward the southern
coast of Mexico.  Interests in that region should monitor the
progress of this disturbance during the next several days.
* Formation chance through 48 hours...low...30 percent
* Formation chance through 5 days...high...80 percent
