How to Tell if a Storm is coming
You’ll hear thunder and see lightning. If you count 30 seconds between hearing the thunder and seeing a flash of lightning you need to be really careful. If the storm is close you may feel your skin tingling and your hair will stand on end.
Lightning Strikes Twice
The idea that lightning never strikes the same place twice is nonsense: it’s looking for the best conductor.
What to Do
You need to avoid carrying or being near anything that’s a good conductor of electricity, and to stay as far as possible from the lightning. Throw away any metal objects you’re carrying. Don’t stand near tall, isolated trees. Don’t stand in water. Try to find low ground and crouch low with your heels touching.
