Hawaii is enduring its most catastrophic flooding in two decades as a severe Kona low storm system continues to inundate the island of Oahu. Governor Josh Green estimates the widespread destruction to infrastructure, including roadways, airports, and a Maui hospital, could exceed $1 billion in damages.
Emergency management officials have ordered the evacuation of approximately 5,500 residents north of Honolulu due to the threat of imminent failure at the 120-year-old Wahiawa dam. First responders have already conducted major rescue operations across the island as forecasters warn of additional heavy rainfall.
The National Guard and the Honolulu Fire Department executed a large-scale rescue on Oahu’s west coast, airlifting 72 children and adults from the Our Lady of Kea’au spring break youth camp. Authorities confirm there are currently no reported fatalities or missing persons, though 10 individuals required hospitalization for hypothermia following exposure to the floodwaters.
The immediate crisis centers on the Wahiawa dam, an earthen structure constructed in 1906 for sugar cane irrigation. Overnight water levels at the facility surged from 79 feet to 84 feet, leaving the reservoir just six feet below its maximum capacity and triggering the evacuation orders downstream.
The dam is currently tied to a Dole Food Company subsidiary, which was fined $20,000 five years ago for delaying mandated safety fixes. The Hawaii state legislature passed a measure in 2023 to purchase the property and invest $26 million in spillway repairs, but the final transfer remains pending a board vote scheduled for next week.
Meteorological data indicates that Kaala, the highest peak on Oahu, recorded nearly 16 inches of rainfall in a single 24-hour period. The National Weather Service forecasts that Oahu will receive an additional six to eight inches of rain over the next two to three days as the storm remains stalled over the region.
State officials report this is the most severe flooding event since the Manoa floods in 2004, which caused extensive damage to residential properties and the University of Hawaii library. Climate researchers note that Kona lows, which draw massive amounts of moisture from the south and southwest, are occurring with escalating frequency and intensity.
