Flash floods are the leading cause of direct weather-related deaths in the State of Hawai‘i. The Big Island averages a damaging flood, caused by heavy rainfall, every 2 years.

Why are floods so dangerous?

• Flash floods can occur within a few hours or even minutes of excessive rainfall.
• People underestimate the FORCE of water. Six inches of fast-moving water can knock you off your feet, and 2 feet of water will float your car!
• Deaths occur when people are caught in rapidly rising flood waters.

HOW TO AVOID BECOMING A VICTIM!

• Listen to your radio for the latest flash flood Watches, Warnings, and Advisories. (*see map)
• Do not camp or park your vehicle along streams during threatening conditions.
• If the vehicle stalls, leave it immediately and seek higher ground.
• Never try to walk, swim, or drive through flood waters.
• If you come upon flood waters, STOP! You will not know the depth of the water nor will you know the condition of the road under the water.

Turn Around, Don’t Drown.

When the leaves of the ‘ama‘u turn toward the upland, it is a sign of flood.
