2013 tornado data added

Good news! On the evening of April 5, 2014 the Tornado History Project added tornadoes for the 2013 calendar year. As always, many thanks to the Storm Prediction Center for compiling and publishing the raw data.

There were 906 confirmed tornadoes in 2013, which is the lowest annual number since 856 tornadoes in 1989. The total number of tornadoes mapped on this site (covering the period 1950-2013) now exceeds 58,000.

As with prior SPC updates, there are also changes to the previously published data (errors are fixed, etc…) However, this year’s update includes an usually large (even more than last year) number of changes that will likely alter the total tornado counts in many years. Updates will be announced here as those changes are incorporated.
