Due to the scale of the floods, the Governor of Hawaii,
David Ige, declared a state of emergency and ordered evacuations all over the state. Flash Flood Warnings, watches, and advisories were also issued by the National Weather Service (NWS). At least a half dozen homes were heavily damaged or destroyed in the flooding, which also destroyed Peahi Bridge, Hanalei Bridge, and heavily damaged Kaupakalua Bridge, and 1 person, carried away by floodwaters, is missing. Overtopping of the dam has now stopped, but the water level remains about 3 feet below the top of the dam. All Maui island parks were closed because of flooding and heavy rains. The
Hana highway was also temporarily closed as it was overwhelmed by floodwaters. Nearly 4000 residents of the Haleiwa town were asked to evacuate. The Waiahole Stream, located above the Kamehameha Highway, reported flow rates of nearly 9,000 cubic feet per second. The previous record, obtained through 19 years of maintaining data, was set in 2012 and was 432 cubic feet per second. The typical flow is around 90 cubic feet per second — just 1 percent of what was observed on March 9. Honolulu firefighters on Tuesday rescued a 27-year-old man after his truck was swept down a stream. He was found standing on the truck's roof. On Wednesday, they suspended another search for an individual a witness saw in a stream in Pearl City. A major landslide occurred on March 11 near the
Hanalei Hill, closing both lanes leading up to Hanalei Bridge. A lightning storm left over 20,000 people without power in Kahala, Kapahulu, Palolo, Waikiki, Manoa, and Moiliili, but the power was restored a few hours later. Due to more heavy rain, the Kalihi stream began rising. Kuhio Highway was the only road leading to the north shore. In addition to the scheduled outage, the Department of Water (DOW) has issued a water conservation request for Hanalei customers on Saturday, March 13. == Aftermath ==
