Uh..."pyro-meso"? This is four hours of the Caldor Fire on the 17th; per current reports today, it's growing and 0% contained. Wonder if there will be pyrotornado warnings on this.

The March 6, 2017 Southern Plains wildfire outbreak is a completely overshadowed and basically forgotten event despite the extent of devastation that occurred. 7 people were killed, 1.2 million acres burned, and at least 87 structures were destroyed. Some fires ran 40+ miles in only 5 hours. In addition, the fires generated at least 2 fire vortices that were visible on radar, the only such case of that occurring on the plains that I know of. One had a rotational velocity of 43.7 kts while the 2nd one had a rotational velocity of 38.4 kts. This Vrot is usually associated with EF1-EF2 tornadoes.

That’s amazing. That’s one of the largest and most well defined pyro tornadoes I’ve ever seen.
I wonder if stuff like this happens more often then we think but only now is it being readily documented. I also wonder if the increase in wildfires due to climate change is also a factor...

Apparent pyro tornado near Weston, Oregon yesterday.
Edit: Actually, this might have been a regular tornado that just happened to be near a wildfire. I'm not completely sure either way.

There were no major wildfires in Oregon recently, that was a tornado from 2018 that passed near a wildfire in Colorado. It was not related to a pyrocumulonimbus so it is not a pyrotornado.

Yup you're right. I saw something about wildfire damage in the SPC report and put two and two together. I'll get rid of the post.

Speaking of pyrocumulonimbus clouds, there are some incredible photos of this New Mexico fire, but AFAIK, no pyrotornado reports yet. I couldn't find any, anyway, but this seems a likely candidate for spawning one -- or does mountainous terrain inhibit those? (I know it doesn't for tornadoes).

Northern NM is very hilly (lived in ABQ for a couple of years back in the 80s).

A day late on this anniversary, but still: the nightmare scenario of a natural pyrotornado going through a major city happened in 1923, per that link.

The Weather Channel has this video of a fire whirl near "a volcano" in Indonesia. It is a fire whirl, not volcanic in origin.

The volcano might be almost anywhere on volcano-studded Java, which is a tinderbox right now at the end of a very dry dry season, but because a flare is mentioned, it's probably Bromo, per this news story (Indonesian, but with video; just click "x" in upper right if an ad appears).

Here's more video and info on the fire, which Twitter can translate (the tweet's text, anyway, and yes, there is a Teletubbies Hill in Bromo Tengger Semeru National Park--Indonesians are amazing).

PS: This volcanic group is gorgeous, and very active.

The fire in question was due to someone using a flare for a pre-wedding event in the Bromo volcanic field.

BMKG Juanda dubbed this event as "dust devil"
