It can lead to a false sense of security... maybe if it turns east instead of north east it barrels into downtown Omaha. In the most extreme case a small tornado in a larger storm that hits no man-built structures may go totally unrecorded. Essentially if you assess tornado risk as something like (frequency * severity) / area, this will under assess risk to a previously developed area that is now being developed. Before there was nothing to hit. Now there is.
