Tornado Archive

@tornadoarchive.com

Tornado Archive is a website dedicated to preserving and visualizing worldwide tornado history, climatology, “archaeology”, and media.

Although not much new information was available for Mexico, the nation's only known violent tornado is now properly recorded on the site. Previously, only the US portion was included, where the tornado caused EF3 damage in Texas.

Over the last few months the content team has been revamping our database system to allow for more frequent updates. This of course has delayed site deployments. Along with US 2025 tors, updates to previous datasets and addition of several more are in the works. We look forward to sharing it soon! 🌪️

1/8/2026 7:10 PM CDT update on the current site outage: we are in the process of a server transition and upgrade that will result in downtime until it is complete. Our previous traffic allowance was exceeded with the old provider. We thank you for your patience during this maintenance period.

We're aware that the tornadoarchive site is currently down and are working to fix the problem. It may take up to 24 hours for the site to come back online. Thank you for your patience.

2024 was a very busy year for tornadoes in the US, so it's taken a while to get all the data processed. We're in the final stages of this task, and the 2024 US data will hopefully be released soon. We're also working on getting updated European data from ESWD, hopefully this summer.

From a forthcoming release: tornadoes in Nebraska, Iowa, Kansas and Missouri on 26 April 2024 along with ERA5 2 m dewpoint, 10 m winds, and MSLP at 20Z 26 April.

In our next database release we will have a data void over the Philippines filled with the Severe Weather Archive of the Philippines (SWAP) dataset. We are thankful of Generich Capuli for donating and maintaining the data! You may view the SWAP project on Zenodo: doi.org/10.5281/zeno...
