Tornado Alert
« on: March 27, 2017, 04:29:15 AM »
Anyone have one of these? I do and I love it. Yesterday, there was a tornadic storm near Denton. I live in north Fort Worth, so I was just within the 30 mile range that it claims and wouldn't you know, it actually beeped, flashed, and said "Tornado Possible". I was thrilled after I had purchased this product from the Home Depot for about 40 dollars and was skeptical of the technology. Not skeptical any longer and looking forward to seeing how it works with lightning, and maybe even closer storms. Highly recommend this product as it detects lightning and tornadoes.

Tornado Alert is a scientific breakthrough based upon over 40 years of research. Unlike existing warning technologies, Tornado Alert constantly monitors the skies in real-time for electrical activity, the scientifically proven cause of tornado formation. Tornado Alert will tell you when a tornado, lightning or severe weather is detected within a 30 mile radius of your location, thatís up to 30 minutes warning with live proximity status, giving you with critical time to get to safety, day or night.


Kinda' vague.  I'd need to know more before spending $70

Honestly it was warning me to tornado activity 15-20 minutes before a warning was issued by the NEW. Home depot has it for much cheaper. I was skeptical as well and could not find anything on the internet about it other than their own page. So I splurged and spent the 40 and it worked very well on a tornado event.

I read that that lightning activity can lead to tornado formation but I didn't know it is now a "proven cause of tornado formation".
That's a big difference. I would like to see the track record of this unit in regards to actual velocity data. If this can predict tornado's 100% then that is a huge game changer.
Guess I have to do some more reading on this.

There was a thread on this a few months ago, but apparently removed. Frankly, I think it's nothing more than a gimmick that may do some good, but I sure as hell wouldn't bet my life on it. If this "proven" technology is actually available to the general public, don't ya think the NWS, WMO, ect. would have employed it long ago? Seriously, technology of this magnitude would have made WORLD news.

You might want to read this AMS paper before getting too excited about this device. The correlation between tornadoes and RF noise is somewhat weak and dependent on circumstances. Yes, it is an old paper, but the physical processes are still the same and the basic methodology seems valid.

I don't mean to be rude to either of you, but I want to know how it worked so well the other day. There was a tornadic storm 20 miles north of me and the device alerted me and said "Tornado Risk" 15 minutes before the NWS issued a warning. I feel like testing it directly is a pretty good way to find out if something works.

There would need to be many, many more than one sample to determine accuracy vs. coincidence.

Eventually somebody will roll a pair!  Meaning the system will be right at some point...

Like everyone here, I am rather skeptical of this device. I would like to see this in action over several years to prove this actually works. Like ocala, I did not know that lightning was proven to cause tornadoes.  To my knowledge, an increase in lightning, either in intensity or types of lightning, does NOT always precede the formation of tornadoes.  I have personally seen instances of having hardly any CC/CG lightning during a tornado to where one could read a newspaper outside at night because of the tremendous amount of CC/CG lightning before and during a tornadic event.

Most recent instance of this happened last Friday night, March 24, 2017 around 10:30-10:35 pm CDT. A upper end EF-1 tornado passed within 100 yards of my house to my SE.  There was some CC/CG lightning with this, but not a lot. There was a Severe Thunderstorm Warning in effect at the time. The tornado was 200 yards wide, traveled 2 miles, and was on the ground for 4 minutes.  We had no warning in terms of lead time prior to the tornado. This circulation showed up on 1 radar scan, despite the radar updating every 2.2 minutes.

In short, this device would have NOT made any difference in terms of advance warning. If one had $70 to waste, I would buy one and take it apart and see what's inside. Finding a AS3595 lightning detector or its equivalent inside the device would not surprise me, given their low cost.

Edit:  Here is a link for the storm chaser communities' reaction (Mostly about like ours here), but there is a post by Lanny Dean about 3/4 the way down explaining the nuts and bolts of this thing. Interesting read on his post.

There are many tools in the market that inform us about the incoming tornadoes and lightning. But some tools provide better and on time notifications as compared to other tools.
