2015 Most Likely The Least Deadly Tornado Year on Record in U.S....Revised!

Update as of 12/30/15

Unfortunately, the holiday weekend proved to be deadly with tornadoes, especially across the Deep South.  There were 26 tornado-related fatalities.  Dallas was hard hit.  Many reportedly died while they were in their cars.  Overall, during this time, more than 40 deaths happened because of either tornadoes or flash flooding. 

It's been an exceptionally quiet year for tornadoes.  In fact, there have been only 10 tornado fatalities in 2015.  If this number doesn't change, it would beat the twelve deaths reported in 1910.

Two sources of statistics were combined to create the long period of record.  The National Weather Service's Storm Prediction Center keeps a file on tornado deaths since 1950.  Also, one tornado historian added to this study with his database going back to 1875.

On average, the U.S. sees 36 EF-3 or stronger tornadoes.  This year there have been just 16.  The violent tornadoes, EF-4 or stronger, usually add up to seven per year.  However, this year, only one happened, just west of Chicago in early April.

It's also interesting to point out, El Nino is known for producing less tornado activity across the nation's mid-section since there's an overall lacking of humidity, winds, and temperatures needed to create the right atmosphere for tornadoes.  But when there's a cooling of the Pacific waters, or La Nina, there tends to be an increase in activity.

But it's important to note the year is not over. Five of the last ten Decembers have brought at least one tornado fatality.  And in December 2010, nine people died because of tornadoes.
