Event narrative (NOAA)
Heavy rain caused the Hanalei River to overflow near the Hanalei Bridge, which then closed Kuhio Highway in that area. Other areas in northern Kauai were affected by downpours that caused debris flows unto roadways, near Princeville, Kilauea, and Wailoko. Other areas that had problems were near Lihue at Niumalu and Hulemalu roads, and in Kapaa where the Keapana Bridge became impassable.
