What the National Weather Service wrote

The Hana Police Department reported a landslide on the Hana Highway. The roadway was

temporarily closed to remove rock and debris. A nearby resort in the Hana area also reported trees downed from landslides.

The wider storm

A cold upper level trough along with deep moisture and southeasterly winds allowed heavy rainfall to develop over the Koolau mountain range of Oahu, over Kauai, and over windward portions of Maui. On Oahu, the heavy rain developed and remained persistent for several hours, which led to flooding and flash flooding over the eastern and northern portions of the island. Particularly the Koolau Mountain Range was impacted. Portions of Maui and Kauai also experienced flash flooding.

Began near Waianapanapa Sp (20.7631, -155.9972).
