MIAMI VALLEY — Several EF-3 tornadoes touched down and caused widespread damage in parts of Montgomery County, Beavercreek and Celina Monday night.
Storm survey teams are working to make measurements that will determine the strength and distance of the tornadoes.
The Enhanced Fujita Scale is the measurement scale used by meteorologists and scientists to determine the strength of a tornado that touches down. >>RELATED: 1 dead from Celina tornado, over 60 storm-related injuries reported at Dayton-area hospitals
