“Hawaiian Electric crews worked throughout the night to restore service to customers in downtown Honolulu and Chinatown and were able to repair one of three transformers damaged by flooding. As a result, power was restored this morning to six buildings, including the State Capitol, state office and city municipal buildings, district court, Central Pacific Bank and First Hawaiian Bank,” the statement said.
Sheets of drenching rain came down as low-lying roads pooled with water, forcing drivers to navigate the flooded roadways.
There was just too much water at one time, which led to flooding, says KGMB/KHNL reporter Lynn Kawano.
Monday was the second wettest day in the history of Honolulu, according to the NWS.
Much of Oahu was getting hit by up to 2 inches of rain an hour Monday. Honolulu, picked up nearly 8 inches Monday, breaking the record for the wettest December day.
“Periods of heavy rainfall will continue across Oahu and Kauai County as a Kona low pulls deep tropical moisture over the western end of the island chain,” the NWS says.
“Rain events of this size can cause catastrophic flooding and affect areas that do not usually flood,” according to the NWS.
Low spots are subject to extreme runoff, which can clog bridges and culverts, exacerbating the already dangerous flooding. Landslides are also expected.
The declaration allows the use of funds “to support state and county efforts in providing quick and efficient relief of suffering, damage, and losses caused by flooding and other effects of heavy rains,” Ige said on Twitter.
The days-long rain event had already left some communities saturated.
Nene Cabin on the Big Island topped the list at 14.07 inches in 48 hours as of Monday night. Keaumo, also on the Big Island, recorded 13.64 inches and Kula on Maui received 12.95 inches.
While the rain is creating potentially hazardous conditions, it may also help Hawaii recover from a drought.
More than half of the state, 56%, is under some level of drought and half of Oahu was under severe drought as of November 30. An updated drought report is expected in the coming days.
