145 first-hand accounts of flood events in Hawaii, ranked by impact. Each is a NOAA-written narrative of the moment.
A cold front moving through the islands and an associated upper air trough combined to trigger heavy showers and isolated thunderstorms, including flash flooding in parts of Molokai, Maui, and Kauai. There were no reports of serious injuries.

Read the full account →With a surface low remaining north and northeast of the state, and a surface trough to the east; heavy downpours occurred in parts of Maui and the Big Island as deep tropical moisture made its way northward.
Read the full account →A combustible mix of surface and upper air instability, and deep tropical moisture, brought periods of strong winds, heavy rain, thunderstorms, and flash flooding to parts of the Aloha State. Lightning strikes led to power outages, and gusty winds toppled trees and power lines.
