What the National Weather Service wrote

Winds, from various directions, gusted over 100 mph during a period that lasted more than one day over the summits of Mauna Kea and Mauna Loa on the Big Island of Hawaii. Winds also gusted over 90 mph on the Haleakala Summit on Maui.

The wider storm

A surface front and a deep upper low, known locally as a kona low, produced heavy and sustained showers and thunderstorms as tropical moisture was pulled north over the Aloha State. The downpours also led to instances of flash flooding. Also, high winds and wintry conditions affected the mountain summits on the Big Island and Haleakala on Maui. No significant injuries were reported. The costs of any damages were not available.
