How does one truly prepare for a torando if you live on the top floor of an ancient dorm?

Prayer. As i was watching the news about the weather and everyone was freaking out because we were supposedly ready to have a tornado any moment, I began to wonder, why do we have natural disasters? Is it God’s way of destroying sin? I think of a natural disaster as God’s way of saying “hey, look I am in control of this world.” just something to think about.
