• 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.

Hello all,
This Sunday a couple of rounds of small isolated storms with short lifecycle (1 to 2 hours) kept poping through the afternoon in my area. GFS showed CAPE at 2500j/kg, Lifted Index around -4 and EHI at -0,5, mostly instability enhanced.
This is the 12Z sounding from São Paulo, about 140 miles to the east-southeast.

The storms were low topped and the radar images showed max reflectivity around 50/55dbz.
One of the storms had a nice wall cloud and it got pretty clear that it had rotation.
Here's the video, 8x faster

Watch video >

Thank you
 
Great southern hemisphere storm. Mirror image of a supercell environment hodograph that we would see here in the northern hemisphere and CLOCKWISE low-level rotation. I'm always intrigued by footage of southern hemisphere storms because we don't see that type of rotation here, unless we get a rare split storm that rotates anticyclonically. Great catch!
 
Thank you! I have to say that since I began this hobby watching videos from up there, reading some texts like the Skywarn guides, etc, I used to get confused with the position of the storm structures haha.
