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 well west-southwest of the southern 
tip of Baja California, and on recently upgraded Hurricane Polo, 
located a few hundred miles south of Manzanillo, Mexico.
East-Southeast of the Hawaiian Islands (Former TD 15-E):
Satellite-wind data indicate the low-level circulation of the 
remnants of Tropical Depression Fifteen-E has become better 
defined, located several hundred miles to the east-southeast of the 
Hawaiian Islands.  Environmental conditions are forecast to become 
conducive for further development, and a tropical depression is 
likely to form around midweek while it moves slowly west- 
northwestward or northwestward.  Interests in the Hawaiian 
Islands should monitor the progress of this system.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...90 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, and a tropical depression could 
form late this week or this weekend 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...medium...50 percent.
