Before you engage in averting behavior, make sure you understand the lightning death numbers. The lightning safety advocacy folks might be out to scare you (Lightning Stats ...):
The National Weather Service is gearing up to promote Lightning Safety Awareness Week, an annual campaign aimed at educating the public about the risk of death and injury from lightning. But the government may want to start by raising awareness in its own corridors, as it can't seem to agree on just how deadly lightning is.
On a Web site promoting the awareness week, a fact sheet filled with exclamatory lightning stats says, "Lightning Kills About 100 People In The U.S. Each Year!" But another page states, "In the United States, an average of 66 people are killed each year by lightning." And the National Weather Service's own stats show that, over the past 10 years, the average number of lightning fatalities has been 45. Deaths haven't topped 53 in a single year since 1996.
