The National Oceanic and Atmospheric Association and the National Weather Service offer the following safety rules for flash flooding:
- When a flash flood warning is issued for your area or the moment you first realize that a flash flood is imminent, act quickly to save yourself. You may have only seconds.
- Most flood deaths occur in automobiles. Do not drive your vehicle into areas where the water covers the roadway. Flood waters are usually deeper than they appear. The road bed may not be intact under the water. Just 1 foot of flowing water is powerful enough to sweep vehicles off the road. If the vehicle stalls, abandon it immediately and seek higher ground. Rapidly rising water may engulf the vehicle and its occupants and sweep them away.
- Do not hike rivers and especially slot canyons while flash flood warnings are in place.
- Do not hike alone and always tell someone where you and your buddy and others are going.
- Get out of areas subject to flooding, including dips, low spots, canyons and washes.
- Avoid already flooded and high-velocity flow areas. Do not try to cross a flowing stream on foot where water is above your knees.
- Be especially cautious at night when it is harder to recognize flood dangers.
- Do not camp or park your vehicle along streams and washes, particularly during threatening conditions.
