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 recently upgraded 
Tropical Storm Polo, located a few hundred miles south of 
Manzanillo, Mexico.
East-Southeast of the Hawaiian Islands (Former TD 15-E):
Showers and thunderstorms remain disorganized in association with 
the remnants of Tropical Depression Fifteen-E, located several 
hundred 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...30 percent.
