Canberra Severe Storm & Tornado 26/01/2013

It would appear that there was a possible tornado reported from severe storms yesterday in Canberra. There is a video on You-Tube here:

    There has also been mentioned that the earlier severe storm south of Cooma was a supercell and i have no doubt this storm will also be classified as a supercell by some. Personally I don’t think any storms from this event classify as proper supercells but this Canberra storm is certainly an impressive severe thunderstorm. The tornado in this video appears to make ground contact briefly and you would get the impression that the cloud behind is wrapping around some circulation but there is no video showing the whole storm base so this tornado is more than likely only a localized circulation on the outflow.

    I have put together a 6 minute video from the Australia Day storms…

    It covers storms down in Cooma ,( I missed most of the Dalgety storm) and also the Canberra storm viewed from the eastern suburbs.

    The Cooma storms took their time to organise but eventually formed into a line of several storms and became marginally severe just east of Cooma,containing a few hailstones to 3cms, mainly 1-2cm( I did originally call hail up to 3- 3.5cm in the heat of the chase, but decided to make a downgrade) Rain was torrential with flash flooding in Cooma, and there were some small hail drifts. The line was riding a boundary and really gathered momentum Northeast of Cooma. Some of the bases today were rather nice and became quite low at times! These had some rapid cloud motion. The lightning wasn’t overly active,until the storm got organised between Cooma and Numeralla. This is when it put down a brief flurry of clear air super charged bolts. Unfortunately I couldn’t quite get ahead of the line again until Michelago, by which stage it had weakened.

    I did however intercept the Canbera storm. From my vantage point, there was some elevated shelf structure and some greenage, but I think the storm had weakened somewhat by the time it reached me… I experienced winds to 50km/h and some heavy rain. The lightning was the main talking point with cgs coming down in every direction with great thunder.

    More storms up around Tarago contained some impressive lightning rates with flash a second at times!

    Hi Michael, I saw a brief video of one of the lightning bolts you saw, it was awesome! The problem with chasing down near Cooma is you would’ve had to speed to get up to the north side of Canberra to get the best vantage point for the later storms. You almost have to pick one or the other and the southern stuff looked better in the models. I would love to see some pics of the early storm near dalgety.

    I could see the differential motion you were talking about, it was a very nice line of severe storms and the lightning in the Canberra storm was very intense!

  • You are probably correct – perhaps more a gustnado making some surface contact. Not sure.

  • Jeff Brislane

    There is now another angle of this “tornado” at Canberra and from this angle it looks like a gustnado and not a true tornado.

    Also there is some speculation of a hook echo to match this “tornado” at 6:10pm. Have a look at the radar here as I can’t see anything except an outflow dominant storm:

    See : 128km Radar Loop for Canberra, 01:00 26/01/2013 to 10:00 26/01/2013 UTC

    A lot of people have also mentioned how fast the storm beared down on Canberra, also a sign of an outflow dominant storm.

    You know, after watching the radar several times I could be convinced the Dalgety storm was a supercell. There is definitely radar evidence that it was a left mover from a storm split and it showed evidence of both moving left and also anchoring in the relative wind flow.

    I hope we will see some images of it just after initiation.

  • Jeff Brislane

    This Canberra storm did interact with the boundary from the southern storms that moved north but that interaction occured over Queenbeyan. You can see a brief intensification on the radar there followed by complete collapse.

  • Hi michael, if this feature meso was taken by you, was it not sufficiently rotating enough for you to film the tornado?

  • Jeff Brislane

    Where about where you and which way were you looking when you shot them Michael?
