For the eastern and central North Pacific east of 180 longitude:

1. Off the Coast of Southern Mexico (EP97):
Showers and thunderstorms continue to show signs of organization in 
association with an area of low pressure located a couple of hundred 
miles south of Acapulco, Mexico.  Recent satellite-derived winds 
indicate that this system is producing near gale-force winds, with 
a better defined low-level circulation.  Environmental conditions 
remain favorable for additional development, and a tropical 
depression or tropical storm is expected to form later today or 
tonight.  This system is forecast to move westward at 5 to 10 mph, 
roughly parallel to the coast of southern and southwestern Mexico, 
and locally heavy rainfall is possible along portions of this 
coastline through Monday.  For additional information, including 
storm warnings, please see the High Seas Forecasts issued by the 
National Weather Service.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 7 days...high...near 100 percent.
