In brief

In the wake of heavy rains, the island of Oahu faces its worst flooding in 20 years, leading to evacuation orders for 5,500 residents. Officials are especially concerned about the Wahiawa Dam, which is nearing critical levels. Despite no reported fatalities, hundreds have been rescued and emergency services are on high alert. With further rainfall expected, the situation remains dire for communities impacted by this disaster.

HONOLULU (AP) — Heavy rains have turned streets into rivers, wreaking havoc on communities north of Honolulu, as state officials move to evacuate thousands of residents due to the risk of failure of a 120-year-old dam. Emergency alerts sounded across Oahu's North Shore, where the flooding has already pushed homes off their foundations.

Authorities issued urgent evacuation orders for individuals living downstream of the Wahiawa dam, known for its perilous condition. More than 230 people have been rescued since the flooding began. The already saturated ground has made it difficult for emergency services to assess the full extent of damages, with estimates suggesting that losses may exceed $1 billion.

The water level at the dam has surprisingly fluctuated from 79 to 84 feet in less than a day, nearing limits that can lead to catastrophic failure. There’s no question that the damage done thus far has been catastrophic, Honolulu Mayor Rick Blangiardi said during a press conference. He added that over 5,500 residents were forced to evacuate as the National Guard stepped in to assist with rescue operations.

No casualties reported yet

Thankfully, no deaths have occurred, though some individuals have been treated for hypothermia. Governor Josh Green emphasized the unpredictability of the weather, stating, It's going to be a very touch-and-go day. Authorities remain on alert as water levels could rise further with incoming storms.

The dam, an earthen structure built in 1906, has been under scrutiny for safety deficiencies for years. Dole Food Company, which was responsible for the dam's maintenance, has faced fines for failing to rectify safety issues in a timely manner. Floods like this one highlight the urgent need for updates and repairs to aging infrastructure across the islands.

Residents have shared their worries about the dam's stability, particularly Kathleen Pahinui, who commented, Just pray for us. We understand there’s more rain coming.”
