Hawaii Flooding and Wahiawa Dam

Heavy rains — up to nearly 16 inches at Oahu’s Kaala peak and 8–12 inches overnight across the North Shore — have produced Hawaii’s worst flooding in about 20 years, prompting evacuation orders for more than 4,000 people (officials say as many as 5,500 north of Honolulu), activation of the National Guard, flooded shelters and search-and-rescue operations using jet skis and airlifts. Authorities are closely monitoring the 120‑year‑old Wahiawa Dam after water ran over the spillway and warned it was "at risk of imminent failure" as more rain is forecast and crews contend with homes swept from foundations and rescue flights impeded by civilian drones.
