Frequently asked questions

Q: Why is that tornado on the list/not on the list of Possible F5/EF5/T10+ tornadoes officially rated F4/EF4/T9 or lower?

A: Every tornado considered for the list had a discussion (some still ongoing) about its inclusion or exclusion from the list. You can view those discussions here and you are welcome to start a new one for any tornado you think should be on the list!

Sawyerville tornado

A 2014 study concluded that the April 27, 2011 Sawyerville EF3 had a kinetic energy output of >120 terajoules, meaning it contained more energy than the Hackleburg EF5, Smithville EF5 (considered one of the strongest tornadoes in history) and Moore EF5s. Does this mean it was potentially of EF5 intensity? ^EF⁵ 01:50, 6 August 2025 (UTC)[reply]

Does it say that it may have been F5 in the study anywhere? Maybe a nice spot on Tornado records is owed to it (well, depending on how many "terajoules" we measure in other tornadoes). Departure– (talk) 02:19, 6 August 2025 (UTC)[reply]

I haven't read the full study, but I'm going to say probably not (at least, not directly). ^EF⁵ 02:27, 6 August 2025 (UTC)[reply]

Every European F5 is now an IF5

The European Severe Weather Database rerated every European F5 as IF5. Алексеев Н. (talk) 18:43, 7 September 2025 (UTC)[reply]
