Hawaii is reeling from what may be its worst flooding crisis in more than two decades. Over the weekend, torrential rains battered both Oahu and Maui, turning neighborhoods into temporary rivers and forcing thousands to flee their homes. The situation feels like a cruel double blow for Maui residents, many of whom are still recovering from the devastating 2023 wildfires that claimed lives and destroyed entire communities.
Governor Josh Green isn’t mincing words about the scale of this disaster. He’s warning that costs could surpass a billion dollars when you factor in damage to airports, schools, roads, homes, and even a hospital in Kula. That’s not hyperbole. That’s the real price of being caught in nature’s crosshairs right now.
When Water Becomes a Weapon
The North Shore of Oahu, famous worldwide for its legendary big-wave surfing breaks, looked nothing like paradise this weekend. Muddy floodwaters engulfed vast areas of the community, lifting homes and cars like they were children’s toys. Authorities had to issue evacuation orders for 5,500 people, though those were later lifted as the initial surge receded.
What made this flooding particularly vicious was the timing. The soil was already saturated from a winter storm just a week earlier. When the new system rolled in and dumped 8 to 12 inches of rain in a short window, the ground simply couldn’t absorb any more water. The result was biblical.
Racquel Achiu, a Waialua farmer, watched her world turn upside down in real time. She was checking on her goats Thursday night when she found them in knee-high water. An hour later, her family’s dogs were drowning in their elevated kennel. Her nephew and son-in-law had to wade through chest-deep water to save them. “My dogs’ heads were literally just sticking out of the water,” she recalled. These aren’t just statistics. These are people and animals fighting to survive.
More than 200 people had to be rescued from the rising waters. The National Guard and Honolulu Fire Department airlifted 72 children and adults from a spring break youth camp on Oahu’s west coast. Think about that for a second: kids on what should have been a fun, carefree vacation instead being pulled from danger by military helicopters.
The Dam Question That Won’t Go Away
One of the most nerve-wracking aspects of this disaster has been the Wahiawa dam, an earthen structure built back in 1906. For decades, this 120-year-old piece of infrastructure has been labeled as having “high hazard potential.” State officials were watching it like hawks over the weekend because a failure would result in “probable loss of human life.”
The dam was reconstructed in 1921 after a previous collapse, and it’s been a source of concern ever since. Water levels spiked and dropped unpredictably as the rains came and went. By Saturday morning, officials seemed less focused on the dam itself and more worried about the broader flooding across the islands, but that underlying anxiety never fully went away.
Here’s where it gets messy. The state has sent Dole Food Company, which owns the dam, four notices of deficiency since 2009. Five years ago, they even fined the company 20,000 dollars for not addressing safety issues on time. Dole responded by proposing to donate the whole system to the state in exchange for assurances that the state would fix the spillway. The company maintains that the dam “continues to operate as designed with no indications of damage,” but when you’re sitting on a structure that could kill people if it fails, “no indications of damage” shouldn’t be good enough.
Climate Change Isn’t Abstract Anymore
Experts point to something called “Kona lows,” those winter storm systems that bring moisture-laden air from the south and southwest. These have always battered Hawaii, but here’s the kicker: the intensity and frequency of these extreme rain events have been climbing, and climate scientists connect that directly to human-caused global warming.
This isn’t some distant future problem anymore. This is happening right now. Islands that have adapted to weather patterns over centuries are suddenly facing conditions that break their historical playbook. When you combine that reality with aging infrastructure like the Wahiawa dam, you’re looking at a compounding crisis that won’t be solved by simply waiting for better weather.
Gov. Green has already been on the phone with the White House requesting federal support. The state needs it. They’ll need it for repairs, for rebuilding, for helping people put their lives back together. But money and federal assistance can’t rewrite the laws of physics or reverse the climate trends that are making these disasters more likely.
People are trying to stay hopeful. Kathleen Pahinui evacuated her home early Friday because of dam concerns, but by Saturday she was already thinking about cleanup and recovery. “Hopefully if we make it through today, then tomorrow will dawn bright and sunny,” she said. There’s something deeply human about that resilience, that ability to look past catastrophe and imagine normalcy returning.
But normalcy might not be the right word anymore. This is the new normal, and Hawaii is learning that lesson the hard way while the rest of us watch and wonder when our turn comes.
