HONOLULU – Hawaii recently faced its worst flooding in over 20 years. Heavy rains fell on already saturated ground after a winter storm just a week before, leading to significant damage and displacement for many residents. Officials are warning that more rain is expected throughout the weekend.
The North Shore of Oahu, famous for its big-wave surfing, was particularly hard hit. Floodwaters surged across the area, lifting homes and vehicles off the ground. As a result, authorities issued evacuation orders for about 5,500 people living north of Honolulu. There were growing concerns that a 120-year-old dam could potentially fail due to the intense rainfall.
Governor Josh Green stated that the damages from the storm could exceed $1 billion, impacting airports, schools, roads, homes, and even a hospital in Kula, Maui. “This is going to have a very serious consequence for us as a state,” he remarked during a news conference.
Most of Hawaii was placed under a flood watch, with areas like Haleiwa and Waialua on Oahu facing flash flood warnings from the National Weather Service. Governor Green also mentioned that his chief of staff had spoken to the White House, assuring that federal support would be available.
Flooding Crisis Overview
The flooding is considered the most severe since 2004, when heavy rains in Manoa caused significant damage. Fortunately, no deaths were reported, and everyone was accounted for, although around ten individuals were hospitalized due to hypothermia.
Emergency crews conducted searches by air and water for stranded individuals, but their efforts were complicated by personal drones flying overhead to capture images of the flooding, as noted by Ian Scheuring, a spokesperson for Honolulu.
In a notable rescue operation, the National Guard and Honolulu Fire Department airlifted 72 children and adults from a spring break youth camp located at Our Lady of Kea’au on Oahu’s west coast. Although the camp was situated on higher ground, officials decided to evacuate the attendees for safety reasons.
The Impact of Rainfall
Governor Green highlighted that the flooding was the worst the state has seen since the 2004 events in Manoa. Although many homes were damaged, a thorough assessment of the destruction was still pending as rescue efforts continued. The mayor of Honolulu, Rick Blangiardi, stated, “There’s no question that the damage done thus far has been catastrophic.”
Officials attributed much of the devastation to the heavy rainfall that fell rapidly on already saturated land. Areas of Oahu received between 8 to 12 inches (20 to 30 cm) of rain overnight, while the island’s highest peak, Kaala, recorded nearly 16 inches (40 cm) in just one day. Forecasts indicate that Oahu could receive an additional 6 to 8 inches (15 to 20 cm) of rain in the coming days.
Concerns Over Infrastructure
One major concern is the aging Wahiawa dam, which has been deemed at risk of imminent failure. Although water levels decreased by late Friday, they were still dangerously close to capacity. Authorities reported that the dam’s water levels rose from 79 feet to 84 feet (24 to 25.6 meters), just 6 feet (1.8 meters) below its limit.
Residents like Kathleen Pahinui expressed their worry about the dam’s safety during heavy rain. “Just pray for us,” she said, knowing more rain was on its way.
The Wahiawa dam, built in 1906, was originally constructed to boost sugar production and has faced safety concerns for years. The state has issued multiple notices regarding deficiencies since 2009 and imposed fines for delayed repairs. While Dole Food Company proposed donating the dam to the state, the transfer has yet to be finalized.
As of now, the dam continues to operate as designed, according to Dole, but the state is actively monitoring the situation as they regulate a total of 132 dams across Hawaii.
