• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

I spotted this video online-its of a waterspout over what appears to be rather shallow water. Why I am posting a link to it, is becuase of what is seen. The waterspout was said to have formed over the land next to the lake-thus a small tornado and moved over the water. The funnel is mostly clear-and due to this you can see it is NOT a single funnel, but many funnels rotating around each other-each funnel is rather small, but the rotational speeds of them are very high, and they all revolve within what most would consider a funnel--I feel this is a video worth studying, as the movements are quite complex, and could further understanding of how a tornado actually operates.

By the look of the vortex structure and movement, I'd put this in the land/waterspout category. Unless I'm imagining things, it looks like it briefly took on a multiple vortex structure which actually is quite common and can even develop in large dust devils.
 
All is true-but the main thing of the video is the movements of the multi vortici within a funnel structure-they are clearly displayed, and perhaps would be of some study value in into the inner workings.

The Eleven-Mile Reservoir tornado was most likely non-supercell. Normally, this would have been an easy call, but ironically, a rare mountain-supercell was just off to the west of this storm. I was working at the flood center in Denver that day and there was some convection up over the mountains. I got called in because a nice storm popped up on the northwest side of town and rode the foothills due south. I was surprised to see the tornado report pop up on spotter network and then have a seemingly innocuous storm be warned. I suppose it is still possible that this storm was supercellular but the radar scan there was showing no elevated rotation.

I saved a radar image of the later supercell which traveled south along the foothills. You can see it here: http://blog.bigskyconvection.com/2008/08/colorado-mountain-supercell.html (Click on the radar image for a large version)

You can see the tornado report well to the southwest of the huge supercell. The radar image came approximately one hour past the original tornado report .

So, I guess I'm just being devil's advocate. The environment was favorable for turning storms that day. However, there is a ton of video of this tornado (including some shot directly below, looking up) ... and all of it makes it appear to be a non-supercell tornado. Youtube it ... seriously. There's a guy on a boat right next to the thing, staring straight up. Gorgeous footage. Definitely looks like a spout.


Reports from that day.

PS: The other supercell had a tornado report ... but no one ever saw it. I could see the wall cloud from my position far to the north, but it eventually got shrouded by the downdraft and I lost sight. (I wasn't chasing, I was on a rooftop downtown Denver at work). There was damage reported, but it could have been RFD tree fall.
