The wider storm

Very heavy showers and thunderstorms generated flash flooding in southeast parts of the island of Oahu. The focus of the heaviest rain occurred over the southern portion of the Koolau Range, resulting in the Manoa Stream overflowing its banks and causing significant flooding in the Manoa Valley, including the University of Hawaii campus. Damages to businesses; to private homes and property; and to buildings and their contents at the university are estimated to be $80 million, though they could go as high as $100 million. On the other hand, no serious injuries were reported.
