Waialua

Waialua is a town located on the North Shore of Oahu, Hawaii. In March 2026, Waialua became newsworthy due to experiencing severe flooding, the worst Hawaii has seen in 20 years. This flooding was triggered by a powerful storm that brought heavy rains to the region. The severity of the flooding prompted evacuation orders for over 4,000 people in Waialua and surrounding areas north of Honolulu, including Haleiwa. A significant concern was the potential failure of a 120-year-old dam, which added urgency to the evacuation efforts. The event highlights the vulnerability of communities to extreme weather events and the importance of infrastructure maintenance and disaster preparedness. Images and videos circulating on social media showed inundated streets and vehicles submerged in muddy floodwaters, underscoring the scale of the disaster.
