The extremely high tornado count during April was driven by two very large tornado outbreaks - the two largest tornado outbreaks on record. This is the most on record for any month, surpassing May 2003 when there were 550 tornadoes. The most active month of the year was April, when 748 tornadoes were confirmed. During the three month period, there 1,150 confirmed tornadoes across the country, the most on record for any three month period. The most active tornado period of the year was the spring season (March-May). The annual total number of fatalities from tornadoes was 551, the most in the 62-year period of record. This ties with 1974 as the most (E)F-5 tornadoes during a single year (Please note that NOAA switched form using the Fujita (F) scale to the Enhanced-Fujita (EF) scale in 2007). There were six EF-5 tornadoes confirmed during 2011, the strongest category on the Enhanced Fujita scale. This places 2011 as the second or third most active year on record for number of tornadoes since the modern record began in 1950, depending on the confirmation rate of the end-of-year tornado reports. As of mid-January 2012, the 2011 confirmed tornado count stood at 1,625, with 93 tornado reports still pending for November and December.
