tfw that's the same siren that was used in my city when it was getting rocketed
I live in Minnesota so I actually hear these for tornadoes. Scariest thing in your life is standing outside in almost pitch darkness at 2:30 in the afternoon, the wind has knocked out all power to your neighborhood and so loud that you have to scream to talk. Only when lightning strikes can you then see for a split second, off into the distance, a 3 mile wide black funnel stretching to the clouds. In the funnel you see shiny glimmers of light which you know are shards of semi trucks, trains etc. that it has already demolished instantaneously. You know that if it comes at you, even in an underground shelter, you'll probably die in a torturous way: brute force, sliced by shards, or ripped apart like a black hole.
And all the while, all you can hear over the screaming wind and the screaming conversation is...
The siren
