Severe rain has triggered major flooding in parts of Oahu, Hawaii. Streets are submerged, homes have been displaced, and evacuation orders have been issued for thousands of residents near the Wahiawa Dam. This historic dam is over 120 years old and is now threatening to fail.
Emergency sirens blared along the North Shore, a place famous for surfing. At 5:35 a.m. Friday, officials advised residents downstream of the dam to evacuate due to the risk of imminent failure. Thankfully, there have been no reports of deaths or injuries so far. Emergency responders are searching for people who might be stranded in the floodwaters.
The damage is significant; some homes have reportedly been swept away, although officials are still assessing the situation. Thousands of residents are affected, and those evacuating are encouraged to carpool due to heavy traffic.
Officials have been monitoring dam levels since a storm last week caused heavy rainfall and widespread flooding, damaging roads and homes. Another storm is on its way, which could bring even more rain.
Hawaii Governor Josh Green activated the Hawaii National Guard to assist with the response. In a social media post, he described the situation as “very severe,” noting that some areas are experiencing chest-high floodwaters.
Currently, most of the state is under a flood watch, with northern Oahu facing a flash flood warning. The National Weather Service warns that these floods are extremely dangerous, especially in communities like Haleiwa and Waialua.
One evacuation center, located at Waialua High and Intermediate School, is under threat from rising waters and is being relocated. About 185 individuals and 50 pets who sought shelter there are being moved to safety.
Recent rainfall has been intense, with some areas receiving between 8 to 12 inches overnight. Residents know this weather can pose a risk. As Waialua resident Kathleen Pahinui prepared to head to a friend’s home on higher ground, she expressed concern about the aging dam. “Just pray for us,” she said, aware that more rain is expected.
The evacuation order now affects over 4,000 people, but officials believe the real number could be higher. Last week, concerns around the dam increased, but at that time, the water levels had dropped.
State Senator Brenton Awa, representing the North Shore, highlighted the rapid development in the area and questioned how this unprecedented flooding would impact the community in the future. The North Shore, known for its stunning waves, has transformed significantly over the years.
Such natural disasters raise concerns about infrastructure. A 2019 report from the American Society of Civil Engineers indicated that Hawaii has 132 regulated dams, primarily built for agriculture. A tragic reminder of the risks came in 2006 when the Ka Loko Dam on Kauai collapsed, resulting in seven fatalities.
In the face of this disaster, community resilience is being tested. The current situation serves as a stark reminder of the importance of emergency preparedness, especially in regions prone to flooding.
