A lot of people dislike this sound, but I like it.

everyone is so chill, the town I live in everyone will be running to try to find the nearest basement!

call me weird, but i'd love to be in Chicago, during a storm warning. those Mods sound so cool echoing the Alternating Wail off all the structures! combined with the Fast Wail of the 2001s, for extra creepiness!

I was visiting for my grandmas birthday and this all of the sudden turns on and it scared to shit out of me so bad I was running down to her basement..

I am from chicago and I was in the hallway of my school during this.

I remember that!!! It scared the crap out of me XD

to be extra creepy have this played on halloween

Awesome ambience!

I went to Chicago, and this happened...

That sounds like a broken police from GTA V

The sirens sound for a reason. Don't ever f*ck with Mother Nature. She can f*ck your day up in a heartbeat 🤗

Oh shoot I remember being in Chicago. And I was just eating somewhere and all of a sudden this came on and I thought i was going to parish. Lol

Federal Signal Modulators doing the alternate wail tone

It sounds beautiful

This is the siren used for real emergencies, and the alert tone is used for tests, so the person recording and the people around them have no care for what is going on

2:13 Someone is talking

Kids be like in 2005 OH no a tornado Kids in 2020 be like OH NO SIREN HEAD

The sirens are only activated in Alternate Wail for tornado warnings.

If I heard the siren during my birthday I would be terrified

Sounds like FS Modulators using an Alert Tone Oscillator wail and a 2001. That's one hell of a way to get the publics attention.

*tornado comes* Sirens: WEWOWEWEOWEOWEWOWEWO Tornado: um I guess imma go now that was probably my longest trip to somewhere *tornado sees timer* Tornado: huh 0 seconds and 0 minutes and 0 hours

If I heard this I would be running for my life.

If I ever heard this once again if there was a tornado warning in chicago I'd be do crazy around this thing

My brain after reading the gashlycrumb tinies for the first time

I was in chicago when that happened i was sooooo scared

Why th is everyone chillin like how many times does this happen a week?

This is on UltraVoice (UV) because the wind up of this alternate wail goes by 4, the wind down goes by 12. The others that is on Modulator Controller (MC), the wind up goes by 6, the wind down goes by 18.

what if you heard that chicago tornado siren that's playing (not the tornado siren) in your area?

This video will probably blow up sometime soon, maybe with one of the next Pecos Hank videos. Those alarms are creepy!

terrorific alarm 😱😱😱😱😨😨😨😨

Alternate wail siren

Federal signal modulator

That is wild. Someone needs to make a song using the sirens.

Tornado: hehe I'm coming >:) Siren: The *fuck* you say? Tornado: I'm coming Siren: *goes off* *Tornado.exe has stopped working*

This is the 3rd video I found on the same day of the tornado

"Do not look at the moon"

OMG! Sounds like an ice cream truck from hell! Lol

When I was a kid I was like is that siren head?

That's the siren head sound but siren head doesn't even exist

I get s**t on that day. It was literally freaking the f*ck out of my face.

When I was 3, 4, or 5.

I’like that How the tornado sirens sound like a talking elephant echoing

All sirens in Chicago, IL: modulators 3012 and 6024 & FS 2001. And FS DSA, Modulator 8032B, Whelen 2910 AND Federal Signal Thunderbolt 1000 (STH-10???) 1 modulator: alternate wail federal signal 2001 - wail

I believe it’s a federal signal modulator

All these people look like they are rushing around trying to get to work on time.

1:00 creepy sounds!

Oh my

The siren will scare the tornado away lol

yeah thats the this is not a test wail

Federal Signal Modulator 6024 doing alternate wail (~1 mile away) and 2001-SRN doing fast wail (~1.8 miles)

I kind off feel bad for Thunderbolts because they have to spin and imagine being spinned for a hour or a minute?

In the game called call of duty mobile2

*Chicago sirens:* *2001* *3 Modulators* *DSA Sirens* *Thunderbolt 1000* *Whelen 2910* *Activated:* *2001: wail* *1 modulator: alternate wail*

Is thish normal in Chicago

It sounds like a police car with a broken siren

Scary 😨

Why are the people not running or panicking?

I will see this howl in my dreams)

3012 alternate wail.

Tornado: lololol imma attack Chicago Siren: goes off Tornado: what the hell is that screech Siren: increases volume Tornado: fuk this shit I'm out

Chill girl- “yeah this is just tornado weather”

Sence the Cthulhu came to chicago i moved out so no where tornados go which is san antonio!! Tx!!

Thats an alt wail not an loop

2:41 it stopped!

When i heard the sirens i just kept eating my subway i didnt give a fuck lmao

not necessary story time One night I was walking from a bus to another when it started pouring so I began to walk a bit faster because I was trying to not get soaked too much without an umbrella. A few minutes later I was right next to a siren and it went off then and there... Part of me was like, should I run away for the tornado and another part was Oh my god this siren is bull crap I can't it's too eerie... I started sprinting because it was too creepy and loud... Part two... Is this particular siren part of more paranormal activities or tornadoes... Because I got home and heard the siren still... I started seeing things in my vision down the dimly lit hallway that looked like shadowy swirl figures (I call them Tornado Creatures) I think its just probably me thinking in the dark side of my brain with the creepy siren just imagining horrific things but later my parents woke me up and said we need to get out of our apartment room for a bit because they saw some person spinning really fast and flashing later that night... I am still really creeped out because of this because it happened the last time it went so if anyone knows what happened that night with the Tornado Creatures than please tell me... I have no video evidence because I dont have a phone and my camera was being fixed so I was unable to record it and see if you guys see them... Although there is security footage of the house I am unable to show it as I have no clue yet on how to post security footage on youtube... The footage in the hallway shows them standing staring blankly at the Tornado Creature who is flashing... And I checked the camera in my room and it had footage of things randomly moving and what appears to be tornado creatures appearing time to time... sorry for the long comment, thanks for the video to help me remember this and post it to the public for answers.
