Here comes version 2.2! This update comes with a few additions, most notably that we now have the 2022 data for the United States up on the site. 2022’s data is as high quality as the last couple years, meaning damage paths and high resolution tracks.

How We Compiled the Pre-1950 US Data
As you may know, some of the data that we used didn’t have coordinates. Thomas P. Grazulis’ Significant Tornadoes, for example, only gave relative locations and directions, not absolute coordinates.
