• A student is looking for help on tropical cyclone prediction. Please fill out the survey linked to this thread: https://stormtrack.org/threads/storm-and-hurricane-intensity-prediction-survey.32957
  • 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.

Tornado's or Gustnado's?

It has a distinct gustnadoish appearance and I don't see any cloud base signs of a mesocyclone, so I would say gustnado.

i'm glad someone posted about this, i actually saw a gustnado the other day when a storm went through except it filled in completely. so i guess you can consider it a landspout if it fills in but doesn't come from a wall cloud? didn't last very long and wasn't very big either. my vote on the pictures is gustnado as well.

Because it's fun, I'm going to go ahead and disagree with Scott. Honestly, I'm not quite sure, but if you use your imagination, in the top picture that could be a very small lowering in the base (more likely a scud, but who can say?) I'd have to know where you were in relation to the storm. Do you have any radar images from then you could post?

There is always the problem of limited view. Having a wide view and most importantly movement (a sense of time and change) would answer the question. From the given pics though, definitely appears like a gustnado. Don't start with the epistemology Ben ;-P.

I would like to see more view of the base of the clouds, but anytime I see a lowering above a rotation on the ground, particularly if that lowering is also rotating, that lends me to support the idea of weak tornado rather than gustnado.

gustnados, in my mind, have no attatchment, no association with the clouds above them.
 
Given that dust whirl is 'rotating violently' under what appears to be a meso (pic 3) I am gonna vote weak tornado. I think I prefer the tornado option, but we will never know. :)
 
I was directly under the lowerings, i'm right in between those two "thingy"'s. Here is a picture of just before the east edge of what i would assume to be the bottom of the wall cloud I was under (notice the funnel):

Directly under that, straight up shot, while those "thingy's" were on the ground.

Looking east after "thingy's" passed over.

same shot again.
 
I'd say Gustnado. In a dry summer like this one, those pop up every once and a while during a nice storm up in the northern tompson region of BC.
