What happened
The episode as NWS HFO wrote it up.
Heavy showers were making driving difficult and dangerous. Drainage systems were having trouble handling all the runoff, so there had been some ponding along roadways, and visibility along the H-1 was very poor in the afternoon. There were no storm-related incidents except for a flooded basement in a downtown Honolulu jewelry store. In Manoa, 2.33 inches of rain fell from 11 a.m. to 5 p.m. Hawaii Kai received 1.24 inches and Waimanalo had 1.92 inches.
