and here is the video – the tornado appears to be over South Hobart
Does anyone have confirmation and damage information from this tornado report. The video here us in a great position but I am finding it difficult to detect rapid rotation although I can clearly see upward motion.
It's a fairly weak tornado, for sure, but I reckon there is definitely rotation (and up motion), Jimmy (did you watch the HD version full screen?). Just imagine being on the mountain there, watching the tornado below you!
Looked like a funnel cloud to me in the HD version. Not sure whether one could say tornado, unless there's a damage path or debris was seen. Pretty rare and exciting for that part of the world. Just hope Tassy can put on another one for when I'm there in December…
There is base rotation in the cloud, it is difficult to detect because of the camera movement but it is actually quite strong. There are a places in the video where you can see it clearly if you jog it backwards and forwards over 20 second intervals. Funnly though the base rotation appears to be anti-cyclonic. The funnel has definate strong upmotion and tight vorticies typical of a tornado. It sits on the one spot for ages so if it is touching the ground, the ground must have been really chewed up underneath, although in saying that it is over a ridge and could still be off the ground. There has to be strong damage from a tornado like this.
Yep Paul Graham I forgot to check the HD version. David assures me there is rotation. One give away regardless was the bowl shaped lowering at least one stage of the video.
