Tornado Days

The Worst Tornado Outbreaks in U.S. History
The eight worst tornado outbreaks in the United States have accounted for nearly $40 billion dollars in damage, are responsible for 17,525 injuries, and tragically over 1,500 fatalities. I wanted to share today a project I have been working on that tells the story of these incredible severe weather outbreaks. Tornado Days, built with the D3.js Javascript library, is an experimental way of exploring these destructive tornado days.

Tornado Days

Many of the outbreaks making the list occurred in recent memory, including three outbreaks in 2011 - the Joplin, MO EF5 tornado, and the massive three day event from April 26 - 28, 2011 among them. This does not include any of the tornado outbreaks from 2013 as data is still very much preliminary, and final numbers have yet to be released.

The visualization requires a modern browser. In fact, it has only been tested as working with Google Chrome, so if you are on another browser - good luck. Not a Chromey? Check out a video of Tornado Days here.
