Tornadoes are a common occurrence in the spring season, especially in certain parts of the country where cold and warm fronts clash together. Before building any kind of shelter or thinking that there will be a tornado every day or that each one will have winds over 100 mph, there are a few facts you should know. A tornado is given an EF rating from 0 to 5 depending on the speed of the winds with the storm. There has been a tornado in each state. However, some states don’t see as many because they don’t have as many severe storms that can cause tornadoes while other states see more than average because of where they are in relation to the jet stream and the storm track that sweeps over the country. These states include Kansas, Nebraska, and Oklahoma. The states in this region of the country are known as Tornado Alley because of the number of storms that are seen each year. While most tornadoes are rated an EF-0 or EF-1, there are larger storms that produce winds greater than 200 mph. These are the tornadoes that can lift homes and cars into the air and slam them down on the ground.
