Grady County southwest of Oklahoma City sits in one of the highest tornado frequency zones in the United States. The county has been struck by multiple violent tornadoes and sits directly in the path of many historic Oklahoma tornado outbreaks. The Washita River creates flooding risk. The county also sits in Oklahoma's earthquake swarm zone. The flat terrain of Grady County with zero natural barriers makes it one of the most tornado-exposed counties in America.
