Severe weather has prompted evacuation orders on Oahu, Hawaii, as flash floods threaten the Wahiawa Dam’s stability. The second major storm to affect the state in a week has led to catastrophic flooding, damaging homes and isolating communities.
Evacuation Orders Amid Flood Threat
Residents in the towns of Waialua and Haleiwa are under immediate evacuation orders. The Oahu Department of Emergency Management (OEM) has indicated that the Wahiawa Dam “may collapse or breach at any time.” Authorities have stressed that individuals should leave their homes without delay, taking only essential items.
- Estimated 4,000 to 5,000 people are at risk near the dam.
- Nearly 10,000 residents in the larger North Shore area are affected by flooding.
As of early Friday, flash flood warnings extend across northern Oahu, with rainfall levels reaching 6 to 12 inches. The OEM has received reports of significant property damage, but exact figures on lost homes are currently unclear.
Emergency Response and Rescues
Emergency crews are actively engaged in rescue operations. Hawaii Governor Josh Green reported that some individuals were rescued from rooftops due to rising water levels. A group of 70 campers was reported safe after being surrounded by floodwaters in the North Shore region.
The Hawaii National Guard has been mobilized to assist with ongoing evacuations and provide support to impacted communities. Emergency responders have faced difficulties accessing flooded areas, as major access routes like Kamehameha Highway and Kaukonahua Road are submerged.
Weather Conditions and Impacts
The National Weather Service (NWS) has declared a flash flood emergency for northern Oahu, warning residents to seek higher ground. The alert described the situation as “particularly dangerous.” Meteorologist Robert Bohlin noted that this flooding event is rare, with the last flash flood emergency issued in March 2021.
This latest storm has delivered an extraordinary amount of rain, with areas receiving two to three months’ worth in just 24 hours. Following previous storms, the ground saturation is exacerbating runoff and increasing the risk of flooding.
Ongoing Weather Warnings
Additional heavy rain may persist throughout the weekend, leading to a flash flood watch in effect until Sunday afternoon. In a broader context, last weekend’s storm inflicted considerable damage across Hawaii, contributing to landslides and power outages, and leaving behind widespread road closures.
- Over 15 inches of rain fell across the state.
- Maui experienced the worst impacts, with elevations receiving over 2 feet of rain.
Governor Green has issued multiple emergency proclamations, establishing a disaster relief period set to last until April 13. As the situation evolves, officials continue to monitor dam levels and coordinate emergency responses throughout the state.
