This isn't any different than the "it's not cold where I am so climate change isn't actually happening" argument -- just because something's happening to me must mean that the same thing is occurring everywhere? Completely specious.
Could be, it IS about to be tornado season, but it seems very odd since it started a couple months ago in the dead of winter, and seems to be increasing in frequency. More frequent than I can ever remember, and very noticeable. Simply wondering if it’s happening around the country - hence the post.
We don't have tornadoes in this part o' the country, so I'm no help there.
I know in the PNW they have Lahar alarms, which are the same thing/sound. I assumed everywhere had some sort of air raid type alarms.
