Portions of Manoa flooded Monday after several days of heavy rain with raging waters getting dangerously close to homes, especially along East Manoa Road.

Flooding is the most common natural disaster in the U.S. — because of this, it is important for you to know what to do before, during and after you are caught in a flood event, including a flash flood.

A flash flood evacuation has been issued for Waialua and Haleiwa due to dangerous flooding and high water at Wahiawa Dam. Residents should leave immediately or move to high ground.

Officials estimate hundreds of homes were damaged or destroyed by the historic storm that inundated the Hawaiian islands this weekend.

Heavy bands of rain and thunderstorms pounded West Maui on Saturday, prompting the National Weather Service in Honolulu to issue a flash flood warning for the entire island that is in effect through 3 p.

Gov. Josh Green said the cost of the storm could top $1 billion, including damage to airports, schools, roads, people's homes and a Maui hospital in Kula.
