| March 2026 | Flash Flood | Kahuku | $10,000,000 | Heavy rain fell over the Koolau mountain range in the middle to later half of the morning, then a thunderstorm developed and anchored itself over the mountains. This thunderstorm then produced a large amount of rain in a short time frame, quickly overwhelming Manoa Stream and sending a flood surge down towards Manoa Valley. Manoa marketplace had nearly 2 feet of water and parked cars were inundated. Homes in Manoa reported flooding and an excavation site quickly became overwhelmed with water and sent mud and debris down the road. The overflowing Manoa and Palolo Streams inundated the entire campus of Hokulani Elementary School in St. Louis Heights and students were evacuated. Large boulders and debris were observed across many roads in Manoa Valley and flooding was also observed across the upper portion of the University of Hawaii at Manoa campus. A home was also flooded in Laie. |
| February 2026 | Flash Flood | Kahuku | $10,000,000 | Heavy rain began falling over the Koolau mountain range early in the morning and became anchored through most of the day. Widespread flooding occurred over much of the Koolau Mountains and eastern areas of Oahu. The following event summary includes a list of impacts that the flooding caused. A man in Kaneohe reported forty inches of water in his backyard with twenty inches of water in his house along the Keeahala Stream. The Kokokahi Gymnasium was reportedly flooded according to the broadcast media. Flood waters reportedly inundated homes in the neighborhoods bordered by the Likelike and Kamehameha Highways downstream of the Hoomaluhia Botanical Gardens. A business was flooded on Kamehameha Highway at the confluence of Opaeula Stream and Helemano Stream. The Likelike off ramp from the H3 Kaneohe-bound was closed due to flooding, and cars were flooded up to their windows. As a result, residents had to be rescued from their vehicles. A family on Kaneohe Bay Drive reported that rapid flood waters washed away the stairs leading up to their home. According to the City and County of Honolulu, a wastewater spill at the Ahuimanu Preliminary Treatment Facility occurred due to heavy rainfall and resulting inflow and infiltration into the wastewater system. |
