A Whirlwind Finish to 2011
By Shrivedog Dec. 22, 2011
With two December tornadoes touching down in the Eastern United States, arguably the wildest tornado season ever experienced in the nation may not quite be over. While 2011 is the second deadliest year in U.S. tornado history, one can speculate that the very accurate 22 minute average advanced warnings saved many lives that would not have been spared had the 2011 season taken place in 1925 (the record year for tornado deaths at 794 and the single-deadliest storm; the “Tri-State Tornado”; Missouri/Illinois/Indiana; of March 18, 1925 with 695 fatalities). Although current technology has made tornado warnings so prolific an occurrence in places like “Tornado Alley” that many people ignored them this year; the proverbial “little boy cried wolf” effect; the fatalities likely would have been in greater numbers had the same storms occurred in the same areas during past decades. What follows are tornado statistics gleaned from the files of the NOAA and current weather reports:
