With summer approaching, we're starting to see an increase in lightning incidents across the country. Through April, there have been 3 lightning fatalities nationwide, which matches the long term average for the first four months of the year, but is more than we've seen at this time of year since 2006. The three deaths so far this year have been people involved in leisure activities (one young boy outside playing; and a father and son that had been fishing). A look at lightning fatalities over the past 6 years (see pie charts below) shows that most lightning victims were outdoors enjoying leisure activities before being struck, and most victims were male. While summer is a good time to enjoy the outdoors, it's important to remember to plan ahead so that you can get to a safe place should thunderstorms threaten. If you hear thunder (even a distant rumble), you're likely within striking distance of the storm. Substantial buildings with wiring and plumbing or hard-topped metal vehicles offer the best protection.

Don't be fooled by the many myths and misunderstandings concerning lightning. Rubber-soled shoes offer no protection. Rain shelters and tents offer no protection. And although metal does not attract lightning, it can conduct the current from a lightning discharge. So, it's important to stay away from anything the plugs into the wall, any plumbing, windows and doors, and corded phones while inside.
