I was listening to a video post where the weather person was saying that this kind of destructive tornado is more typical of the mid-western states, especially those in "tornado alley". The damage and loss of life is really sad to hear about. I have family in Wichita, KS and they have a "safe room" in their house. It's essentially a bunker where the walls, floor and ceiling are all made of reinforced concrete. It has a steel door that even has the jambs filled with concrete. When the weather threatens they've got a good shelter and given the number of severe storms they see in an average summer, they use it often. Best of luck to any of you who have been affected by the storms.
