According to the NOAA National Severe Storms Laboratory, flash floods are the number one weather-related killer in the United States. Flash floods can occur within a few minutes of excessive rainfall. You may have only seconds to act, so please keep in mind the following safety tips that can help save your life:

• Nearly 50 percent of all flash flood fatalities nationwide involve vehicles. Saving your life can be as easy as turning your car around when you see water on the road. Never attempt to drive through flooded roadways. 
• Even in relatively shallow water, tires can act as flotation devices, lifting up big vehicles and sending them downstream. It takes only two feet of water to float a 3,000-pound car. 
• Beware that water covering roadways may hide washed-out bridges or gouged-out roadbeds. If you attempt to drive across, you may not be driving on a road. 
• In rainy weather, be alert and stay tuned to local radio or TV.
• If you are in a low-lying area when flooding is occurring, get to higher ground quickly, and be sure to avoid canyons and washes that can channel swift water.
• Do not attempt to cross flooded roads or streams on foot. It can take as little as 6 inches of water to knock an adult off his or her feet. Furthermore, water may be flowing more rapidly than it appears. 
• Never allow children to play near ditches or storm drains.
• During stormy weather, do not camp or park vehicles along streams or washes.
• Be especially cautious at night when it is harder to see flood dangers.
