In Salt Lake City, lightning has killed three people and injured three more since 1995.
By contrast in Utah County, no one has died from lightning over that same period. However, three people were injured and lightning caused $165,000 in damage. Davis and Weber counties were even safer, with no deaths in either and only one injury between them.
Now, obviously Salt Lake City is bigger in terms of population and development, so it makes sense that it'd also experience more destructive lightning strikes.
But things get weirder when we go statewide. Specifically, Grand County had the same number of deaths as Salt Lake County, and only one fewer injury. And other parts of the country that are much more densely populated than any county in Utah southern California, for example had fewer strikes.
There are surely a lot of factors at play here, from climate to behavior, but for now the map gives us a sense where this seemingly most unlikely of accidents is prone to happen.
