The strangest vortex

[Damien49]

Hello,

After some years of absence, I'm back with a new case very strange. The former being a curious hybrid between landspout and gustnado, visible here: http://stormtrack.org/community/threads/landspout-or-gust-tornado.26532/

But this is even stranger.
No photo, just a video:

It's unlike anything known.

Here a video capture :

I think smoke that was caught in the circulation of what's called a 'gustnado'. A gustnado is a weak vortex that forms along the edge of outflow. Often squall lines or downbursts. I think this one would have been invisible except it found some smoke to suck in. It doesn't look like condensation, cloud.

Yes I think so. The assumption seems to me the most likely is this is not a condensation cloud. But then, this is indeed the storm circulation that is causing the vortex form of the smoke.
