Tornado reported in Australia 20th January 2005

[Jimmy Deguara]

Hi.

Nice tornado reported near Coonabarabran, New South Wales eastern Australia. An F2 maximum intensity. Interesting that it was slightly higher based. I like the rain free base and circular structure - no doubt about it!!

All the parameters were in place on this day for tornadoes - it was just a case of finding the tornado.

That's a cool picture. I like the collar cloud around the funnel.
Thanks for posting.

Did anyone get any pictures or video of the actual tornado? I don't see a tornado in any of those shots. Any Aussie chasers get this one?

 

[James Harris]

Unfortunately there were no chasers in the area at the time so the only footage and photos is what is on those websites. I know myself and Jimmy were on the southern section of the line it formed on .
Might try and see if they have any other footage of it.

Shane,

The area is infested with trees too. One section around there makes the jungles of southeast Oklahoma like dream chasing country. The only view you have open space is up and down the road - that's it for at least 40 miles. Not sure exactly where this occurred as it seems it's a little more open.

There were several microbursts in the mess further south with extensive tree amd limb damage.

Cool wall cloud, Jimmy!
From tree damage with a lot of probabilities it's an F2. However, no structural damages?

 

[Stuart Robinson]

Looking at the images of the cloud structure I was confused for a while :?

Until I remembered that every thing rotates in the opposite direction in the southern hemisphere.

Hi Andrea,

F2 is likely. The tornado was slow moving. Don't think there was any form of structural damage at all. Can anoyone here comment on the scour marks? Can this by any chance be much a stronger tornado eg F4? Any comments would be much appreciated.

Regards,

The scour marks would probably have more meaning if the tornado were moving faster; but here, it would probably have time to scrub that part of the ground. And they appear to be from a singular circulation as opposed to multiple vortices, which, in a circulation of this size, would be responsible for the violent damage.

Also, the tree damage doesn't really look like what one would expect for a violent tornado — all the branches seem to be tossed around in the vicinity of the trees they came from, and they all appear to have a good deal of leaves on, which probably wouldn't be the case otherwise.

They were my thoughts too - thanks Thomas. Someone was trying to suggest on another forum that it was a "significant" tornado.

Try this for an LP supercell observed yesterday just west of Sydney.

Wow! Pretty cool pics Jimmy. I just looked at it in a mirror to make it look right :lol:

Do my eyes deceive me, or is that a mid-level funnel cloud in this picture?

Unbelivable LP, Jimmy! :wink:

Some great captures there Jimmy, love the one with the CG ripping out the side.

NSW has done fairly well this year in terms of severe storms. The outbreak in early December was a great start however what has got to me is the fact that Western Sydney managed to cop an LP Supercell on the 2nd of Feb yet the next day an HP moved through the northern suburbs with suspected Tornado damage in a couple of suburbs. 2 Days in a row of 2 completely different types of Supercells !

One of my fellow Sydney Storm Chasers, Daniel Weatherhead, managed to capture some fantastic shots of the LP from the 2nd. Love the clarity of the pictures !

Hi James and Dann,

Yes it is great that photographs were taken of this storm - I got my photographs done today actually from the LP supercell.

Here are some video stills from yesterday's supercell:

An HP supercell developed and moved through the Sydney suburbs dropping violent winds and very large hailstones let alone the very heavy rainfall. A possible weak tornado is being investigated.
