Most tornadoes only last a few minutes, but the longest-lived tornadoes may, in rare cases, persist for more than 3 hours. Unless a tornado is unusually slow-moving, though, it will not stay over the same spot for very long. The average tornado moves at about 30 miles per hour. At that speed a mile-wide tornado would only be over a given spot for two minutes. Some tornadoes do move very slowly, and may even stop moving completely.
