After Flooding Remember that flood conditions change rapidly and severe flooding can develop in minutes. Flood water levels can be much deeper than they appear. The depth of water may be difficult to assess. Only two feet of water can cause a car to be swept away, and as little as six inches can cause unstable footing. Do not walk or drive through flood waters.
More people drown in their cars during a flood than anywhere else.
Floods and storms can also knock down power lines. If you lose power, never use a gas oven, range, barbecue, hibachi or portable propane heater to heat your home. These units give off deadly carbon monoxide. Carbon monoxide poisoning has caused several deaths during previous storms this year. If you see downed power lines, do not try to repair or grab them.
