Kona low triggers life-threatening flooding on Oʻahu’s North Shore, Hawaii

"Catastrophic flash flooding affected the North Shore of Oʻahu, Hawaii, as extreme rainfall

produced by a slow-moving Kona low inundated communities in Waialua and Haleiwa, prompting evacuations and emergency response operations under life-threatening conditions.
Preliminary rainfall estimates indicate totals exceeding 330 mm (13 inches) in approximately 12 hours across parts of northern Oʻahu, with rainfall rates of 25–50 mm (1–2 inches) per hour reported. Approximately 127–254 mm (5–10 inches) fell within the first six hours, intensifying runoff and rapidly overwhelming drainage capacity." W
