The National Hurricane Center is issuing advisories on Tropical 
Depression Three-E, located about 1800 miles southwest of the 
southern tip of the Baja California peninsula.

1. An elongated area of low pressure located several hundred miles 
southwest of the southern tip of the Baja California peninsula is 
producing disorganized showers and thunderstorms.  Development, if 
any, of this system is likely to be slow while the system moves 
generally westward at about 10 to 15 mph.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.

2. Disorganized showers and thunderstorms located a few hundred miles 
south of the southwestern coast of Mexico are associated with a 
broad area of low pressure.  Environmental conditions are forecast 
to be conducive for development, and the system is likely to become 
a tropical depression within the next couple of days while it moves 
west-northwestward parallel to the coast of Mexico.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.
