The wider storm

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.
