My goodness! When you said the church walls had been damaged I imagined a little weatherboard church. This one has substantial double brick walls! It appears that the windows may not have been able to withstand the "suck" and took large sections of the walls with them.
A couple of other observations (from here in my living room, of course!):
1. Some of the trees near the weatherboard house on The Channon Road show twisted tops.
2. The tornado appears to have taken a sharp left turn as it strengthened. I wonder if this is reflected in the storm motion as a whole?
3. It appears that the church may have been in the path of the tornado just after the multiple-vortices re-combined into one funnel. Is it possible that when a tornado goes through a multiple vortex stage, it may be an indication of intensification of the tornado?
An interesting severe weather event and I am sure much can be learnt from it because Jimmy was there on the spot!
