For the eastern and central North Pacific east of 180 longitude:

Western East Pacific (EP98):
Showers and thunderstorms associated with a broad area of low
pressure located well southwest of the southern tip of the Baja
California Peninsula remain disorganized. Environmental conditions
appear conducive for additional development of this system, and a
tropical depression is likely to form this weekend as it moves
westward at 10 to 15 mph across the western East Pacific.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...high...80 percent.

Showers and thunderstorms associated with the remnants of Tropical
Depression Fifteen-E, located more than 1000 miles east-southeast
of the Hawaiian Islands, have increased somewhat this morning but
remain disorganized. Environmental conditions appear conducive for
some development of this system as it moves westward to
west-southwestward, and a tropical depression could form well to
the south or southeast of the Hawaiian Islands by the middle to
latter part of next week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.

A broad area of low pressure located about 800 miles
south-southwest of the southwestern coast of Mexico is producing
disorganized shower and thunderstorm activity. Environmental
conditions are conducive for development, and a tropical depression
is likely to form late this weekend or early next week while it
moves gradually north-northwestward and northward off the coast of
southwestern Mexico.
