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 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 day or so 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 toward the middle 

portion of the 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.

For the North Atlantic...Caribbean Sea and the Gulf of America:



Central Subtropical Atlantic (AL95):

Showers and thunderstorms are slowly getting better organized in 

association with a low pressure area centered about 400 miles 

southeast of Bermuda. Further development of the low is possible, 

and this system could become a short-lived tropical depression or 

storm during the next couple of days while it moves northward and 

north-northeastward, well northeast of Bermuda.

* Formation chance through 48 hours...medium...50 percent.

* Formation chance through 7 days...medium...50 percent.



Eastern Tropical Atlantic:

A tropical wave is expected to move off the west coast of Africa on 

Monday, and an area of low pressure could form in association with 

the wave early this week. Environmental conditions are forecast to 

be marginally conducive for development, and a tropical depression 

could form by the middle to latter portions of the week while the 

system moves generally westward at 15 to 20 mph across the eastern 

and central tropical Atlantic.

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 7 days...medium...50 percent.
