At 11:00 am the storm had matured proceeding to make a left-shift in its course, a clear sign of its severity. The Moree radar images captured at 11:20 am, 11:30 am & 11:40 am show a clear hook echo. It is within this period with which the supercell has the hook echo that it passes over Millie.

As the supercell passes southeast of Moree in interacts with a developing storm approaching from the north. The storms crashed into one another sapping their intensity.


As the cell regenerated it continued over Warialda. As it passed east of the town it produced distinctive damage to a forested area. One local posted "Trees thousands of them torn out or stripped to the point where we can now see Gragin peak." sharing images of the carnage.

The unique pattern of damage evident in the picture below is typical of a tornado. On close inspection the trees have been felled in multiple directions. Significantly, trees on the left of this picture have been felled towards the right, while on the far right of the image we can see a tree has fallen towards the left. This convergence of damage is clear evidence of a tornado being the responsible weather phenomena in this event. The degree of damage to the area of forest pictured is consistent with winds in excess of 145 km/h (expected winds of 175 km/h) equating to a tornado of EF1 intensity.
