A tropical disturbance developed in the Western Pacific Ocean along the eastern periphery of the monsoon trough in mid-August. Located at 33° north, it steadily organized, and became Tropical Depression Sixteen-W on August 15 while located to the northwest of Honolulu, Hawaii. It moved eastward along the west–east-oriented surface pressure trough, and crossed the International Date Line later on August 15. Abnormally warm sea surface temperatures allowed the system to intensify despite its unusually high latitude, and it became Tropical Storm Wene on August 16. It quickly attained a peak intensity of , but weakened due to colder sea surface temperatures and wind shear. Wene continued to weaken, and dissipated when the storm merged with an extratropical cyclone.
