For the eastern and central North Pacific east of 180 longitude:
Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Odalys, located located over a thousand miles west-southwest 
of the southern tip of Baja California, and on newly formed Tropical 
Depression Seventeen-E, located a few hundred miles south of 
Manzanillo, Mexico.
East-Southeast of the Hawaiian Islands (Former TD 15-E):
Showers and thunderstorms have increased, but remain disorganized, 
in association with the remnants of Tropical Depression Fifteen-E, 
located more than 500 miles to the east-southeast of the Hawaiian 
Islands. Environmental conditions are forecast to become more 
conducive for development of this system by the middle to latter 
portion of this week, and a tropical depression is likely to form by 
that time to the south or southeast of the Hawaiian Islands as the 
system moves generally westward at 10 to 15 mph. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...high...70 percent.
South of the Gulf of Tehuantepec:
An area of low pressure could form in a few days to the south of the 
Gulf of Tehuantepec. Thereafter, environmental conditions appear 
favorable for gradual development while the system moves slowly 
west-northwestward to northwestward, parallel to the coast of 
southern and southwestern Mexico. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
