2012 data added

Though this announcement is a little late, effective April 15, 2013 the Tornado History Project added tornado data for 2012*. There were 940 confirmed tornadoes last year, which is the lowest annual number since 2002 registered 932 tornadoes. The total number of tornadoes mapped on this site (covering the period 1950-2012) now stands at 57,154.

There were also a relatively large number of changes to tornadoes in prior years, but unlike similar updates in the past, a itemized list will not be given. Instead, if you have previously downloaded data, simply re-download to get the most up to date information.
