I was able to interview a BoM storm spotter in Bendigo who saw the tornado. He was less than 200 metres from the tornado, which extended from a very low cloud base to the ground. He said it could have been up to 100 metres in width. He said the tornado was very clear as it was so dark with loads of debris. He also commented that as he watched the storm approach from the northwest that the cloud structure was such that it looked as if it had 'rotating swirls'.

From an assessment of the damage path that I undertook yesterday I would say that much of the damage was consistent with F1 on the Fujita scale, however I was surprised at the smaller pockets of damage, such as trees uprooted and eucalyptus trees near 1 metre in diameter being totally snapped in half - leading me to suggest the tornado could have reached the lower end of the F2 scale. Perhaps one of the most astonishing bits of damage I saw was a beam of wood (100mmx200mmx6000mm - required 4 men to lift) from the roof of a house that was thrown in the opposite direction from the storm movement across the road and fortunately landed in a bit of vacant land. For me this was a sign of the enormous energy this tornado must have had - Incidently it was not far from where I believe the tornado initially touched down.

The most serious damage could be confined to a width of 50 to 100 metres that extended for almost 7 km across the northern suburbs of Bendigo.

Although I haven't done a comprehensive analysis of the volumetric radar my initial assessment of the event is that a supercell spawned the tornado. Interestingly the cell on radar lasted for around 2 hours, however the structure from radar is hard to interpret due to the distance from the radar - also the Dividing Range combined with the earth's curvature means that the lower portions of the cell cannot be obtained.

From a meteorological perspective there was certainly enough shear in the lowest 10000ft for storm organisation, yet the CAPE was lower and 'skinny'. In fact it probably has more charactersitics of a 'coldie' than a warm season severe thunderstorm - perhaps a hybrid!

I heard Rod Aikman interviewed on ABC Radio and thought that he was 'sensational'.
