Rainfall totals at some locations on Hawaiʻi Island surpassed one foot as Iselle passed over the island overnight and into this morning.

Twenty-four hour rainfall totals ending at 8 a.m. on Friday, Aug. 8, show more than 14 inches of rain at Saddle Quarry and Kulani; more than 12 inches of rain at Hakalau and Puaakala; and 13.9 inches in the Glenwood area, according to data compiled by the National Weather Service.

The greatest rainfall total on Maui was at Puʻu Kukui in the West Maui Mountains, which received a total of 5.36 inches.

Mike Cantin with the National Weather Service said there was heavy moisture stuck and wrung out over the Big Island. During a morning press conference as the storm was making its way over the island, Cantin explained, “What’s happening is the center is moving away, but all the moisture is being wrung out. It still is moving west -– it’s just that the moisture is stuck in place,” he said.
