Fact: Although they can be highly destructive, tornadoes everywhere are extremely rare compared with other weather hazards a location can face, Carbin says. And they occur on small geographic scales. Even in Oklahoma or Nebraska, "you can go a lifetime without seeing a tornado," even if one struck a few miles away, he says. They may be more common in some parts of the country than others, "but the probability of an event in any one location is very small," he says.
