Hawaii Flooding: North Shore Evacuations & Dam Concerns – UPDATED
Hawaii’s North Shore Submerged as Flooding Prompts Evacuations, Dam Failure Threat
The famed North Shore of Oahu, Hawaii, a global epicenter for surfing, is grappling with catastrophic flooding as torrential rains overwhelmed the region overnight and into . Evacuation orders have been issued for residents in Waialua and Haleiwa, with some already stranded as floodwaters rapidly rose, engulfing streets, homes and vehicles.
The situation escalated with warnings of a potential failure of the 120-year-vintage Wahiawa Dam, raising the stakes and prompting urgent calls for residents to seek higher ground. Governor Josh Green issued an evacuation order for Waialua and Haleiwa, emphasizing the severity of the conditions. “We have issued an evacuation order for Waialua and Haleʻiwa. If you are in these areas, please evacuate now and follow guidance from emergency officials,” he stated. “We are seeing dangerous conditions, including catastrophic flash flooding on the North Shore and the potential for dam-related impacts in Central Oʻahu. Please do not seize this lightly — stay off the roads, avoid floodwaters, and check on your neighbors.”
Videos circulating online paint a grim picture of the devastation. Footage from Hawaii News Now showed Ke Iki Road, a key artery running alongside some of the world’s most iconic surf breaks, completely inundated. A witness described the water level reaching as high as his armpits – and he stands at 6’6”. Other videos depict cars submerged in floodwaters at Ke Iki Beach, with authorities advising those trapped to remain in place and avoid attempting to navigate the treacherous conditions.
The flooding began late , and intensified overnight, impacting multiple streams and gulches including the North Fork of Kaukonahua Stream, Poamoho Stream near Kaukonahua Highway and Dole Fields, Kiikii Stream in Waialua, Mohiakea Gulch, the Anahulu River, and Helemano/Opaeula Stream near Haleiwa. The National Weather Service issued a Flash Flood Warning at 8:22 AM HST, citing reports of the imminent dam failure. An HNL Alert followed at 8:34 AM, warning of “life-threatening flooding” in downstream areas.
An emergency shelter was initially opened at Waialua High and Intermediate School, but was subsequently evacuated to higher ground as the floodwaters continued to rise. The Honolulu Department of Emergency Management issued a stark warning at 9:00 AM: “WAHIAWA DAM HAS NOT FAILED BUT IS AT IMMINENT RISK OF FAILURE. Potential life-threatening flooding of downstream areas.”
The potential failure of the Wahiawa Dam is a particularly concerning development. Built 120 years ago, the dam’s structural integrity is now under intense scrutiny as it struggles to contain the unprecedented volume of water. The situation is being closely monitored, and officials are preparing for the possibility of a breach, which could exacerbate the already dire flooding conditions.
The North Shore, renowned for its legendary waves and annual surfing competitions, is now facing a different kind of challenge. The flooding has not only impacted residential areas but also threatens infrastructure and the local economy. The extent of the damage is still being assessed, but the region faces a long road to recovery.
Residents are being urged to heed the evacuation orders and prioritize their safety. Authorities are advising against travel in the affected areas and are urging people to stay informed through official channels. The situation remains fluid, and updates will be provided as they grow available.
