Active Systems: 
The National Hurricane Center is issuing advisories on Tropical 
Storm Iona, located in the central Pacific basin well west-southwest 
of the Hawaiian Islands and Tropical Storm Gil, located well 
southwest of the southern Baja California peninsula.

Well South-Southeast of the Hawaiian Islands (CP92):
Disorganized showers and thunderstorms associated with a trough of 
low pressure located about 650 miles south-southeast of Hilo, 
Hawaii, continue to persist. While the system currently lacks a 
well-defined low-level center, some development is possible during 
the next day or so. By this weekend, environmental conditions are 
expected to become less conducive for further development.

An area of low pressure is expected to form well southwest of 
southwestern Mexico within the next day or two. Environmental 
conditions appear conducive for some gradual development of this 
system, and a tropical depression is likely to form late this 
weekend or early next week as the system moves west-northwestward at 
10 to 15 mph.
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 7 days...high...80 percent.

An area of low pressure is forecast to form offshore of the coast of 
Central America and southern Mexico by the middle part of next week.

to 15 mph.
