The probability of being struck by lightning in the USA is approximately 1 in 250,000 per year, translating to about 1,000 strikes annually among a population of 250 million. Staying indoors during thunderstorms significantly reduces the risk, while being outdoors increases the likelihood, especially in open areas or near tall trees. If caught outside without shelter, crouching low to the ground and covering ears can help mitigate the effects of a nearby strike. Over a lifetime, it's likely that individuals will know someone who has experienced a lightning strike. Awareness and precaution are essential for safety during thunderstorms.
