The National Hurricane Center is issuing advisories on Tropical 
Storm Lala, located well north of the Papahanaumokuakea Marine 
National Monument, on Tropical Storm Moke, located a few hundred 
miles south of Hilo, Hawaii, and on newly formed Tropical Storm 
Iselle, located several hundred miles south-southwest of the 
southern tip of the Baja California Peninsula.
Central East Pacific (EP91):
Disorganized showers and thunderstorms are persisting with a broad 
area of low pressure located well to the south-southwest of the 
southern tip of the Baja California Peninsula. Environmental 
conditions could support the development of a short-lived tropical 
depression during the next couple of days before it becomes 
absorbed by Tropical Storm Iselle.

An area of low pressure is expected to develop well south of the 
southern tip of the Baja California Peninsula during the middle 
portion of this week. Some slow development is expected thereafter, 
and a tropical depression is likely to form later this week or over 
the weekend while the system moves generally west-northwestward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...high...70 percent.
Well Offshore Southern Mexico:
Another area of low pressure could form well offshore of Central 
America late this week. Environmental conditions appear favorable 
for gradual development over the weekend as the system moves 
westward to west-northwestward at 10 to 15 mph well offshore of 
southern Mexico.
* Formation chance through 48 hours...low...near 0 percent.
