For the central North Pacific...between 140W and 180W:

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.

Well East-Southeast of the Hawaiian Islands (Former TD 15-E):
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.
