The storm stretch comes as the Kona low weather system drags tropical moisture over the islands, raising the threat for at least a foot of rainfall in the hardest‑hit areas.
Governor Josh Green issued an emergency proclamation on Monday. "A Kona low weather system is expected to produce prolonged heavy rainfall that could lead to flash flooding statewide, with the highest likelihood of flooding impacts across the smaller islands and urban areas," a news release from Green's office said.
Now, the website Power Outages is reporting on the failures impacting customers across the state. As of reporting on Saturday morning, there were more than 120,000 customers without power in Honolulu.
Honolulu was the hardest hit area. The East of Honolulu is reliant on power lines bringing electricity to the area from Windward Oahu. According to a report from Hawaii New Now, these transmission lines have been damaged, impacting service in the area.
But the outages are reaching across the state, with more than 7,000 people in Maui without power, and more than 4,000 people on Hawaii Island without power. Over 130,000 customers were without power as of press time on Saturday morning.
Electric crews have been able to identify and restore power to 29,000 customers in parts of Waikiki and East Honolulu.
However, some customers are expected to be without power overnight.
Hawaii News Now reported that the power outages are impacting traffic lights, and drivers are advised to treat impacted intersections as four-way stops.
The National Weather Service (NWS) has issued a warning of flash floods, which will be in effect until 12:30 a.m. HST (8:30 a.m. ET).
Locations that will experience flash flooding include: Hawaiian Paradise Park, Hawaii Volcanoes National Park, Wood Valley, Pahala, Volcano, Glenwood, Punaluu Beach, Kawa Flats, Mountain View, Naalehu, Hawaiian Acres, Orchidlands Estates, Keaau, Pahoa, Hawaiian Ocean View, Fern Forest, Eden Roc, Fern Acres and Waiohinu.
Residents are advised to stay away from bodies of water such as streams, rivers, drainage ditches and culverts—even if they are currently dry.
The NWS said in its warning that the flash flooding is life threatening.
NWS's Weather Prediction Center meteorologist Scott Kleebauer previously told Newsweek:
"A powerful Kona storm will produce periods of hazardous weather impacts across the Hawaiian Islands through the weekend. Expect a combination of threats ranging from significant flash flooding, damaging winds, snow and ice over the highest Big Island summits and strong to severe thunderstorms."Though Kona lows can happen at this time of year, NWS meteorologist Maureen Ballard previously told Newsweek that the current strength and length of impact is considered rare.
The NWS is regularly sharing updates on social media as the storm continues.
Kleebauer told Newsweek that the storm will begin to lift northwards on Monday, and unsettled weather will begin to ease.
