What the agency told people to do
For your protection move to an interior room on the lowest floor of a building. If on or near the Great Salt Lake, get away from the water and move indoors or inside a vehicle. Remember, lightning can strike out to 15 miles from the parent thunderstorm. If you can hear thunder, you are close enough to be struck by lightning. Move to safe shelter now!
