Hawaii Flooding: Rescue Efforts Continue After Historic Rainfall

Honolulu, HI – Rescue and cleanup efforts are underway across the Hawaiian Islands following days of torrential rainfall that triggered widespread flash flooding. The flooding, described as the largest Hawaii has seen in 20 years, has led to thousands of evacuations, widespread power outages, and over 200 rescues as of Monday, March 23, 2026.

Flash Flooding Impacts Oahu and Neighboring Islands

Relentless rain began impacting the islands over the weekend, peaking on Friday with over 20 inches of rainfall reported in some areas. A Flash Flood Emergency was issued due to concerns about the potential failure of the Wahiawa Dam in Honolulu County, prompting evacuation orders for Waialua and Haleʻiwa. While the dam remains stable as of Saturday, March 22, 2026, authorities warn that continued rainfall could raise water levels to a threatening level.

The Hawai‘i National Guard has activated approximately 200 soldiers and airmen to assist with rescue and support operations across all counties. First responders have been working tirelessly to aid residents stranded by rapidly rising floodwaters.

Rescue Operations and Community Response

As of Friday evening, nearly 196 people had been rescued, with over 80 individuals rescued from campsites on O’ahu. Residents are now focused on cleanup, with many homes left with standing water and significant mud damage. Mac Burton, a resident of Waialua Beach, described the devastation, stating that anything below four feet in height was “completely wiped out.” Burton and other community members spent Sunday helping neighbors shovel out mud and debris, despite ongoing power outages.

Governor Green Addresses the Crisis

Hawaii Governor Josh Green described the flooding as the largest the state has experienced in 20 years, since the Manoa flood of 2004. He stated in a press conference on Friday evening that the state is leading rescue and shelter operations, with support from the Federal Emergency Management Agency (FEMA). FEMA is working closely with Governor Green and Hawaii Emergency Management Agency (EMA) to provide assistance and protect communities.

Looking Ahead

While evacuation warnings have been lifted for vulnerable areas downstream of the Wahiawā Dam, officials are urging residents to remain vigilant as stationary bands of heavy rain continue to pose a threat. Cleanup efforts are expected to take months, and the community is rallying to support those affected by the devastating floods.
