Floods are the most common hazards in North Central Texas. There can be many causes of floods - heavy rainfall, soil saturation, inadequate drainage, and more.

Flood vs. Flash Flood - what's the difference?

Flash flooding occurs as the result of heavy rain events and happens very quickly. Regular flooding occurs as the result of a more prolonged rain event, lake overflow, or dam failure. 

Flash Flooding Safety Tips

  • Avoid already flooded areas, especially those with high-velocity flow.
  • Move to higher ground if you are in an area subject to flooding. Do not park your car along rivers and streams, particularly during threatening conditions. 
  • Never drive through flooded roadways or by barricades.
  • If your vehicle stalls, leave your vehicle behind and seek higher ground.
  • Be especially cautious at night when it is harder to recognize flood dangers.
