Weather Update: Flooding in Oahu, Hawaii
Severe flooding has necessitated widespread evacuations on the north shore of Oahu, Hawaii, marking the most significant flooding event in the state in two decades.
The Oahu Department of Emergency Management issued evacuation orders early Saturday morning for approximately 5,500 residents in the Waialua area, emphasizing the potential failure of the last accessible road if heavy rainfall persists. Reports confirm no fatalities; however, 200 individuals have been rescued, and ten have been hospitalized due to hypothermia. Additionally, a youth camp operated by Our Lady of Kea’au was evacuated, with 72 individuals airlifted as a precautionary measure.
The Wahiawa dam, constructed in 1906 and identified as a high hazard potential structure, poses significant risk. Recent assessments indicate water levels rising to within 1.8 meters (6 feet) of its maximum capacity. The dam has been under scrutiny following a $20,000 fine in April 2021 for maintenance deficiencies. A 2023 state law aimed to transfer ownership to Hawaii, but this process remains incomplete.
Reports confirm no fatalities; however, 200 individuals have been rescued, and ten have been hospitalized due to hypothermia.
Further rainfall is anticipated across the Hawaiian islands in the coming days, with projections of an additional 15 to 20 cm (6 to 8 inches) on Oahu. The flood damage, already substantial, is yet to be fully evaluated. Honolulu Mayor Rick Blangiardi noted the impact on hundreds of homes and described the situation as catastrophic.
