You can also download the data now, using the share tab! Note that European data is not available for download.

A status update as some have inquired recently: the data for 2023 tornadoes is currently being processed and QC’d for addition to the website. Environmental data is also being added for these dates. We appreciate your patience as we update with the approach of spring 2024!

As an add-on from yesterday, a bug in the database development pipeline caused more detailed tracks from pre-1950 tornadoes (e.g. for Grazulis' F5 events) to be overwritten in the web version over the last several months. This will be corrected in the upcoming update.

Tornado Archive v2.3 is out! Includes 2023 data! Tornado Archive

As others have forwarded on their personal accounts, we are pleased to announce that Version 2.3 has been made live including new 2023 (international) data, bug fixes to pre-1950 tornado tracks, and narrative comments to many tornadoes. We hope you enjoy!

50 years ago today, the Super Outbreak of 1974 occurred. A very large and powerful storm system spurred 148 tornadoes across 13 states and one Canadian province, 7 of them rated F5 and 23 of them rated F4. At least 310 people were killed and over 5000 were injured.

We are very excited to announce that the paper led by Malcolm Maas describing our site/database and its utilities has been accepted for publication in BAMS and is now in EOR! A big thank you to all involved in the process! The preprints can be seen here: doi.org/10.1175/BAMS-D…
