Honolulu, Hawaii – Massive rainfall totals exceeding 25 inches have overwhelmed parts of Hawaii, triggering widespread flooding and dangerous runoff across multiple islands in just six days.
According to the National Weather Service in Honolulu, Oahu recorded some of the highest totals, with 25.21 inches measured at Kaala and more than 18 inches in several locations including Punaluʻu Stream and Moanalua. These extreme totals led to significant flooding, especially in low-lying and urban areas where drainage systems were quickly overwhelmed.
Maui and Molokai also saw intense rainfall, with Puu Kukui picking up 19.61 inches and parts of Molokai exceeding 22 inches. On Lanai, totals topped 13 inches, while the Big Island recorded nearly 9 inches in Laupahoehoe. Even Kauai, typically wetter, saw widespread 3 to 5 inch totals during the same period.
Emergency officials report that saturated ground from earlier storms worsened runoff, allowing water to rise rapidly in streams and waterways. In Honolulu and surrounding communities, floodwaters covered roads, stranded vehicles, and forced some evacuations.
Residents are urged to remain cautious near streams and avoid flood-prone areas even after rain ends, as runoff can continue for hours.
While conditions have begun to improve, officials warn that additional rain early next week could renew flooding concerns across the state.
