Lightning: A Deadly Weather Hazard

Thunderstorms are impressive displays of the power of nature. However, they are also extremely dangerous.

On average, according to NOAA, lightning claims the lives of 27 people every year in the US and seriously injures hundreds more. To date in 2019, lightning has killed 12 people across ten states. The most recent victim was struck on Sunday in Richarton, ND. Local officials say the man was outside doing volunteer trail work at a recreation center when a storm moved through the area.

Lightning comes in a variety of forms, but the cloud to ground variety is the most threatening to people. A typical bolt carries a current of about 300 million volts and can heat the air around it to 50,000°F. That is five times hotter than the surface of the sun.

This type of lightning, NOAA says, strikes the US about 25 million times a year. However, 70% of lightning fatalities occur during the summer months. The season marks not only the peak of thunderstorm activity in the United States, but also the time of year when people spend more time outdoors.

According to a NWS report on lightning deaths in the US from 2006 to 2017, the vast majority of victims were men engaged in an outdoor leisure activity. Listing a variety of different pastimes at the time they were struck, fishing topped the list as the most deadly water-related recreational activity.

To avoid becoming a statistic, follow the advice of the NWS – “When thunder roars, go indoors.”
