What do we do to prepare for storms?

What we have done to make us more safe in a thunderstorm we have made houses more sturdy so the winds don’t take it down. Another thing is we build houses out of different materials sometimes unlike wood so the lightning doesn't. Make sure not to stay in water. Stay 15 feet away from others.

Do not have any metel with you when there is a thunderstorm.
