Guess what type of US weather event is the most deadly, by far, using a ten-year average ?

“Fog related motor vehicle accidents 

average about 31,000 annually, 

injuring 11,000 and killing 500 

– that mortality is greater 

than deaths attributable to 

heat, floods, lightning 

and tornadoes combined.”
