In the United States it used to be on the first Wednesday of each month during the summer they would run a tornado alarm. Namely it was to test the alarm system, to make sure that everything was working.
And we knew if it was Wednesday and the first Wednesday of the month I mean. And those alarms went off we knew not to worry too much about it.
For some genius reason they decided to run them on different days, it’s pretty much just random at this point. Which is stupid because the only thing it does is makes everybody ignore the alarm.
You are 100% correct. I worked in Oak Ridge for ten years. Twice in that time the alarm went off on a day other than the first Wednesday. I shit myself a little both times, and that’s how it should be.
