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 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.
