According to the National Weather Service, more deaths occur due to flooding each year than from any other severe weather related hazard. The main reason is people underestimate the force and power of water.
More than half of all flood-related deaths result from vehicles being swept downstream. Remember, flash flooding can take only a few minutes to a few hours to develop. Be prepared to take detours and adjust your route due to road closures if there is standing water. As little as six inches of water may cause you to lose control of your vehicle. Flood water may be much deeper than it appears as the roadbed may be washed out. Be especially cautious at night when it is harder to recognize flood dangers.
