How to Avoid Floods

Avoiding Flash Floods

• 1

  Understand the danger. The United States Geological Survey defines a flash flood as "The result of heavy or excessive amounts of rainfall within a short period of time, usually less than 6 hours, causing water to rise and fall quite rapidly." Watch for these signs.

  Watch for areas of danger near dry creek beds or bridges. Flash floods can arise quickly, so avoiding these areas is a key part of avoiding a flood. Remember that just 6 inches of flood water can knock you off your feet.

  Change your driving route to avoid moving water. Two feet of rushing water can move away most vehicles, including SUV's. Cars can stall when driving through as little as 6 inches of water, leaving you stranded and in danger.

• 4

  Move campsites to higher ground when rain is evident nearby. Rainwater upriver can lead to flash floods even when it is not raining in your location. Listen to the National Oceanic and Atmospheric Administration (NOAA) Weather Radio for watches and warnings and use common sense.

• 5

  Remove your boat or canoe in potential flash flooding circumstances. A tranquil river can turn into a raging, debris-filled flood in a surprisingly short time. The potential danger is not worth the excitement. Even seasoned swimmers can be trapped in debris or undercurrents during a flood.

Avoiding Other Floods

• 6

  Build on high ground. Have a professional surveyor evaluate your building location before breaking ground.

• 7

  Consult with insurers as to flood plains and flood insurance eligibility. Many communities have a flood plain management plan that will help you avoid building in a frequently flooded area.

• 8

  Know the difference between a "Flood Watch" and a "Flood Warning." A Flood Watch means that conditions are favorable for flooding. A Flood Warning means there is currently observable flooding and danger is imminent.

  Remember tsunami risks when swimming at an ocean beach. Tsunamis are caused by earthquakes in the ocean or near the coast and result in massive waves and flooding. If the water recedes quickly and unexpectedly, seek high ground immediately, since a tsunami is likely imminent.
