145 first-hand accounts of flood events in Hawaii, ranked by impact. Each is a NOAA-written narrative of the moment.
As a weak tropical disturbance with abundant low-level moisture moved through the islands, an upper low moved in from the northwest. This combination generated heavy showers and thunderstorms, which then resulted in flash flooding over Maui, especially in the Iao Valley.

Read the full account →The combination of upper-level instability and tropical moisture, some of which were remnants from former Tropical Storm Ulika, generated heavy rain and isolated thunderstorms over the parts of the Big Island of Hawaii, Maui, and Oahu.
Read the full account →With a surface trough northwest of the islands and an upper trough over the western part of the state, heavy showers and thunderstorms developed in a very moist environment. The downpours led to flash flooding conditions on Oahu for a time on the 25th and early on the 26th.
Read the full account →With plenty of moisture near the surface and unstable conditions aloft, heavy rainfall and isolated thunderstorms developed across much of the state. Flash flooding occurred on the Big Island of Hawaii, as well. No serious injuries were reported.
Read the full account →The combination of a nearby surface low and upper trough brought heavy showers and thunderstorms to parts of the Aloha State, mainly Kauai, Oahu, and Maui. Some of the rainfall was enough to cause flash flooding in a few instances.

Read the full account →An upper trough moving toward the Aloha State from the northwest acted on a pocket of low level moisture moving through the islands to produce heavy showers and isolated thunderstorms, mainly affecting Oahu and the Big Island of Hawaii.
Read the full account →An eastward-moving trough developing near Kauai caused showers and isolated thunderstorms to form over parts of the Aloha State, with Oahu seeing the heaviest downpours producing flash flooding.
Read the full account →As a middle- and upper-air feature tracked near the islands, heavy rain again fell over portions of the state. A flash flood occurred on Oahu, as well.
Read the full account →More heavy rainfall and isolated thunderstorms developed over parts of the island chain as Lane moved away from the state to the west. Some of the precipitation caused flash flooding on Kauai, the Big Island, and Oahu.
