Studies have shown most people struck by lightning are struck not at the height of a thunderstorm, but before and after the storm has peaked. This shows many people are unaware of how far lightning can strike from its parent thunderstorm. If you hear thunder DO NOT wait for the rain to start before seeking shelter, and do not leave shelter just because the rain has ended.
