• 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.

2011 Tornadoes in Review

Neat map, but I notice that the 5/24/11 tornadoes (e.g. EF5 W and NW of Oklahoma City, EF4 NE of Chickasha, etc.) don't appear on the map, or at least not in their rated intensities. What data did you use to create the animation?
 
Hi Jeff:

I will have to go and look at the database to see what may have went wrong. I am using NWS LSRs to make the animation. It appears (just from memory) that a few other reports may be wrong as well. The most likely explanation is that they were either input into the system wrong (or preliminarily) and have not been changed yet.

I'll echo that comment. It seems many notable dates are not correctly represented, including some EF2s and EF3s in Nebraska from June 20th. You'll want to check your data, as you already mentioned.
 
Yep, it appears as if the generated LSRs were generated prematurely and not updated in the IA State archive. I may shoot an e-mail to the admin to see if there are any plans to update the database...
 
I would consider using NCDC's storm events database archive instead.

IEM is the only database that has reports in shapefile format. You can get CSV files from the daily SPC logs, but putting them all together for everyday would be very time consuming. NCDC storm events database is always delayed by two months...
 
It's actually *not* more accurate...I'm not going to argue about the deficiencies of storm reporting here, but I've seen plenty of "storm data" hiccups in recent years.
