Flash Flood in Maui County, Hawaii

Early in the morning of March 22nd, heavy rain moved over Maui and led to flooding across the island. Many roads were flooded and landslides were reported. Keawe St. was closed in both directions between Kupuohi St. and Kuhua St. due to flooding. Both lanes of Honoapiilani Highway were blocked near mile marker 33 due to a landslide. Kahekili Highway was closed from 2120 Kahekili Highway to Kahakuloa due to flooding. Kapunakea St. and Front St. intersection was closed due to flooding. Kahekili Highway was closed from 2120 Kahekili Hwy to Kahakuloa due to flooding. Hana Highway/Hanakai St. to Hanakai Alamaha St. was closed due to flooding. Many other roads across Maui were closed due to the flooding.

A cutoff low moved in from the northwest and pulled deep tropical moisture from the south over the Hawaiian islands. This led to the development of prolonged slow moving heavy rain and thunderstorms. The heavy rain and thunderstorms caused catastrophic flooding over Oahu's North Shore and Manoa Valley.
