How to interpret this page
These are whole tracks selected by their recorded touchdown area, not all tornadoes that affected that area. The linked map also includes tracks recorded as ending in or crossing the selected state, so its count may be higher. A border-crossing track's rating and dimensions describe the whole event and may reflect conditions beyond that border. Earlier reporting was less complete, especially for weaker tornadoes.
