The Fujita scale is a system that’s used to rate how much damage a tornado caused. Notably, a strong tornado can have a lower Fujita scale rating than a smaller tornado if the latter caused more damage. While more than 80% of tornadoes in the United States are considered weak, it only takes one striking the right place at the right time to cause significant damage. If you have a home or business that was destroyed by a tornado, you’ll likely need to turn to your insurance for help.
