How many tornadoes hit the United States yearly?
About 1,000. The actual average is unknown, because tornado spotting and reporting methods have changed so much in the last several decades that the officially recorded tornado climatologies are believed to be incomplete. Also, in the course of recording thousands of tornadoes, errors are bound to occur. Events can be missed or misclassified; and some nondamaging tornadoes in remote areas could still be unreported.
