Significant Tornado Events - Global Edition

Can anyone verify the accuracy of this? MetSul posted the death toll update on X today, but I’m unclear on if it’s the overall outbreak total, includes non-tornado fatalities, or is just from the Rio Bonito tornado itself.

There are seven confirmed deaths in Paraná: six in Rio Bonito do Iguaçu and one in Guarapuava, all related to the tornado. In addition, 20 injured people remain hospitalized. There was also one death in Rio Grande do Sul, but it was not related to the tornado.

Additionally curious to what the "extreme damage" refers to. If they're implying what i think they are (regarding higher end intensity and even rating consideration?) I'm gonna be wowzered. Some of the damage haven't FULLY came out yet despite the F4 rating so we will see

Anchored homes being destroyed, scouring (allegedly, although I think it's debris craters) and a few other things.

Eh, then i take back the part about it being higher end intensity. Sounds mostly like a sporadically violent tornado within multi vortex structures. Most tornsdoes like that struggle to produce violent winds (Hollister and Essex were large, disorganised circulations that couldn't consolidate) whereas you have tornadoes like Greensburg and Rio Bonito where it isn't a fully consolidated core but still strong enough to produce violent winds

What makes you say that? It was certainly higher-end, destroying concrete buildings and sweeping away large portions of an elementary. Hollister was just a weak tornado and for some reason the aloft rotation didn't translate to surface rotation.

Sweeping away large portions of a elementary? Now i didn't know that! In my general depiction, "extreme" means possible EF5 intensity or higher end EF4.

My point about Hollister and Essex was unrelated to intensity for the most part but was more about how large wedges never typically consolidate a very intense core except a few. In this case, concrete buildings being destroyed is EF4+ but extreme for me generally means around that intensity but it isn't far fetched to say HE EF4 intensity was reached perhaps briefly with this tornado.

I’m assuming no students were in the building when this happened. Otherwise this could have been a Moore 2013 type tragedy.

No, the tornado hit at ~5:00 p.m. and it was out of session. I'm assuming that's some sort of gymnasium, given it went quite easily.

I've continued mapping out the tornado's path via Sentinel-2 imagery, taking inspiration from Nick Kraz's less-detailed but more consistent map (he's been mapping it in the style of Fujita's 1970s-80s damage path maps, it's really cool). The tornado started a pretty significant distance west of town, causing visible tree damage for miles. The imagery ends east of town so it's impossible to say when the Guarapuava F3+ dropped.

Classes had ended at 5 p.m., and there were approximately 500 students at the school. A regional sports event was scheduled to take place inside the school at 8 p.m., with around 1,000 people expected to attend. It was very fortunate that it didn’t happen at another time.

I'll have to use overlaying more often in the future, I think this project made me realize that geolocation might be a skill of mine that I've never had to use. Third image is slightly off but not by enough that it significantly affects the track (it's on a bank, which warps the image).
