Ohio ranks within the top 20 states in the nation for fatalities, injuries, and dollar losses, indicating that it has a relatively high likelihood for damages resulting from tornado. Tornadoes are vigorously rotating columns of air that are in contact with both the surface and storm clouds. Typically, they are in the shape of a funnel surrounded by a cloud of debris and dust which makes them extremely dangerous in populated areas. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are approximately 250 feet (80 m) across, and travel a few miles (several kilometers) before dissipating. It is difficult to predict the exact location of tornadoes therefore risk assessments are done using historical information and past declarations.
