The USA in the past 12 months has seen the fewest number of tornadoes since at least 1954, and the death tolls from the dangerous storms have dropped dramatically since 2011.
Just two years after a ferocious series of tornado outbreaks killed hundreds of Americans, the USA so far this year is enjoying one of the calmest years on record for twisters. Through Thursday, tornadoes have killed only three Americans in 2013; by the end of May 2011, 543 Americans had died.
The seven people killed from May 2012 to April 2013 is the fewest in a 12-month period since five people died in September 1899-August 1900, according to Harold Brooks, research meteorologist with the National Severe Storms Laboratory in Norman, Okla.
