Flash Flooding

A tragic event: at least nine people were killed by a flash flood in Arizona. It was sunny with no sign of rain, but a storm upriver generated it.


Here is advice from the National Weather Service:

On average, more people are killed by flooding than by any other single severe weather hazard, including tornadoes, lightning, and hurricanes. Most of these deaths occur at night, when it is more difficult to recognize flood dangers, and when people are trapped in vehicles.
