Really those tornados are so random it's hard to know what to do. You aren't going to have an F4 storm anyway. It's going to be a small one that touches down at random. Best place for you is the bathroom or a closet. But, you can't sit in a closet or a bathroom for hours on end.
and no where on our ground floor is an internal room, they're all outside rooms with windows. Seriously, houses around here aren't built for this madness.
It seems like nothing happened though
But the movie was good
