Funny that, us too over the weekend. [yes, the UK gets tornadoes]... including some impressive rain and hail. We had one definite one on Saturday, and one that was trying to be tornado, but didn't quite make it.

Scary looking green/yellow/blue sky though. I now know what tornado weather looks like.

It's supposed to be late winter/early spring here, not summer thunderstorm weather.

Point... on the other hand, I'm not sure if the old rules still apply.

Someone changed the rules.

Ain't that just the way.. just as you think you've got it figured out... they change everything!

Tornadoes; Not just for Kansas anymore.. :P

Here in the 'Emerald City' everyone's lawn has died, because watering your lawn is not something we've had to do before. And east of the mountains is all on fire..

I never water my lawn. It dies, it grows back. Because grass.

I'd often wondered about that. Good to know.

Our tornadoes steer *away* from town centres and trailer parks. They're not rare, but anything greater than F1 is.

Holy SHIT, Den!

I've never seen a tornado "in person", but I've seen a lot of videos, and this one is just weird. Every other tornado I've seen started up in a cloud, and then descended to the ground. This one looks as if it starts at ground level, like a "dust devil" - at times it isn't even visible, except for the bits of debris. But that vortex actually is connected to a cloud - but you can't see it! There's an invisible tornado between the cloud and the ground!

I love Australia... everything there is weird... ;-)

We invented Fire Tornadoes. Why not invisible tornadoes?

This was a weak tornado - F1 at most. It had a funnel cloud but it didn't quite reach the ground. The wind did, though. You can see the funnel in other photos.

Most "fire tornadoes" are really "fire whirls", which form in a very similar fashion to dust devils - the rising column of heated air from a fire picks up some spin from straight-line winds that are also caused by convection. Only if the fire is big enough to create a pyrocumulus or a pyrocumulonimbus cloud above it, and the fire whirls rise up into the cloud, does it qualify as an actual tornado. (Alternatively, a genuine tornado may develop out of either a plain cumulonimbus or a pyrocumulonimbus, and as it wanders over the burning area and sucks in some flames, it will become a fire tornado for a while.)

I suspect that there are fire tornadoes forming here and there over the northeastern US at the moment...

How it appears and disappears is the frightening part! Yowsa!

I've seen dust devils before but never a vortex without the cloud bank/mesocyclone (at first) !
Fascinating and scary at the same time- it's good you can see the debris to know it's there.
