A closer look at these two major outbreaks showed that many tornadic storms traversed large areas. Tornadoes occurred in counties upstream and/or downstream from falsely warned counties. Often times these warnings gave the public in the impacted downstream counties even greater advanced warning. Thorough post storm analysis by Science and Operations Officers indicate that most of the falsely warned counties fall into the category of strong indications of a tornado, and given the same conditions these experts would issue a tornado warning the next time. Additional, false alarms can also be attributed to the county-based verification method. If a warning covers portions of four counties, and the tornado only touches down in one of the four warned counties, three false alarms are counted. The False Alarm Rate (FAR) is impacted by several factors that do not relate to warning performance.
