Let me start this blog by saying what this isn't. This is NOT a NOAA weather radio. What this is is an electromagnetic detector that locates and measures EM fields in the area. Every storm produces an electromagnetic field and the larger or more severe the storm the stronger the EM field. the company states that this can detect potential severe weather 30 minutes sooner with a 95% accuracy and can locate them within 30 miles of the detector's location. It has an alarm system consisting a loud siren and a strobe light. You must locate the unit on an outside wall away from electrical fields such as TV, radios, computers and even away from its own AC adapter. Also, if it can be placed in or near a window that would be highly acceptable.
Once set up it will run a self test to tell you if you have it in a good location. If it is then all you have to do will be let it on. It will display a "No Threats" screen to let you know it's working (see below).
Quite warm today for late October and we had a strong cold front come through in the late afternoon. I almost forgot about looking at the Tornado Alert until almost too late. There was lightning nearby and when I checked I got this on the screen.
The bars just past half way indicate the lightning was somewhere in the range 4-6 miles from me. there was closer strikes, but like I said I almost forgot to look at this and when I did the bulk of the storm had shifted east. Besides lightning there was heavy rain and some wind. Nothing more than a typical garden drenching Tstorm. The unit called it right...NOT SEVERE.
Just wanted to post this to show I haven't forgotten this, but our severe season is technically done. I will post if something pops up unexpected like today. Otherwise we'll just have to wait.
Well, the 2017 Severe Weather season in SE Pennsylvania got off to a bang yesterday. We had a real doozy of a cold front come through with temperatures dropping from a high 73 to 51 in about 20 min. Numerous warnings came out, so it was a good day to keep track of the Tornado Alert warning system.
When I first looked at the module, it read "not severe" which is its way of telling you that what is occurring is a typical garden afternoon thundershower. It was as a small cell passed close by, heading NE ahead of the front with a few flashes and a rumble or two of thunder. Ah, but the best was yet to come.
As the front roared closer, the unit upgraded to a severe storm (dangerous conditions). The bar graph indicated to me the storm was still a distance away, possibly 10-15 miles. In checking the radar that was about the story. So I decided to keep checking every so often.
