The best way to react to a severe flood situation is to do the exact opposite of what you would do in a tornado. In other words, seek the highest possible ground.

The inclination to run -- or drive -- away from rising flood waters is understandable, but it's also dangerous. As little as 6 inches (15 centimeters) of rising water can be enough to sweep a person off of his or her feet, while just 18 inches (46 centimeters) of rising water can carry a vehicle away [sources: National Weather Service, Tamayo].

Downed power lines from a hurricane or tsunami can still be live, leaving you one false move from being lit up like a firecracker on the Fourth of July. Hopping behind the wheel also poses its own set of hazards. Floodwaters may hide debris, potholes and other damage that could make roads impassable. If your car stalls, abandon it immediately and head for high ground [sources: National Weather Service, Tamayo].
