Scary!!! Tornado warning in Fort Worth, Texas with Sirens 

This is terrifying but fascinating at the same time

the green color is the heart of a supercell mesocyclone, the updrafts is so strong in this area the rain gets sucked back into the atmosphere repeatedly and creates hail, the reflection of the ice, clouds, and sun make the color look green. This area is the dead center of the supercell and where the updraft is strongest, typically you wont have much wind at all in this area on the ground because the wind is literally going up, as opposed to down or side to side. The rear flank is where the rear flank downdraft is located and where the wind is usually strongest. Rotation occurs near the rear flank where the updraft and downdrafts meet and cause rotation, sometimes becoming so strong and tight that a tornado forms. My advice is if you ever see a sky that looks like this above or even near you take cover

Your under arrest tornado, disturbing the peace and vandalism.

wow! Can't believe it took that long to get the sirens going!

The only thing that scares me is if it is in Chicago The sirens there sound like hell

I love how the tornado has to be doing damage BEFORE they realize, " Oh. Forgot the sirens. Oops." That just happened Moore, OK (of all places) this April. The TV networks and spotters were livid!

I'd be running for shelter when hearing the sirens yet everyone comes out to look and record!!!!

Exactly. It's fun to watch these videos and hear different sirens, see different events, chase yourself, etc. However, it is a WHOLE different story when the storms come to you and there is nothing you can do. When those sirens sound, and you know it is heading your direction; your entire attitude changes VERY quickly.

green sky means you're fucked. I remember the season this year. We went to the church to take cover, This shit is pretty intense.

Remember people - tornadoes tend to be on the bottom far edge of supercell storms. Just because it has already started raining/the rain is subsiding doesn't mean the threat is clear.

My family and I watched as a funnel cloud started forming in the distance, clearly a tornado forming. We called the police and told them that they needed to issue a tornado warning, they told us and I quote "A warning cannot be issued unless a tornado is already on the ground" so muffed up!!

Dude I was working as a cart attendant at Sam's club when this shit hit and my stupid ass manager told me to go back outside cuz it wasn't that bad....fortunately she was fired two weeks later for life endangerment of an employee lol

Look! A tornado is going to rip apart my house and possibly kill me! Better grab my camera!

The tornado sirens here if Fort Worth sound horrifying, especially when a storm looks like that!

You don’t need sirens with clouds like that.

Great filming!! I couldn’t help but notice how eerily quiet it was (despite the tornado sirens) as the storm was moving in. The calm before the storm. I subbed!!

When the sky turns that sickly blue/green color, you know you are in deep shit. Scary stuff...

Somehow the concept of lightning safety is being lost on the guy standing in the back of the red truck

This tornado came right through my neighborhood when I was really little It’s the storm that gave me my intense fear and fascination of storms

I remember this! I was 4 months pregnant and we lived off of Eastchase in Fort Worth @_@ A bit far from it, but the weather was bad that day in DFW. Those sirens always scare the shit out of me....

I remember when these sirens went off I was waking up from a nightmare as a little boy and my mom shouted at me to go to the storm shelter under the stairs. I was so cranky haha. Good times.

If this were to happen on December 21st, 2012 in every state that would be freaking scary as hell

The color behind the clouds is just stunning. good job.

I remember when my baby was 1 years old and talking on the phone to my husbands mom she asked me if the storm was there yet I told her what storm look out the front side as I walk out did not see nothing then decided to look in the backyard and saw a huge dark sky coming toward us before you know it that storm blew up a real big that was the scariest time of my life I live in westworth village which they call it Fort Worth Texas. I love your video.

Ah, Fort Worth weather. My favorite. I been though at least 3 tornados. The tornado sirens aren't scary. You get use to them. And the greenish clouds are just beautiful.

I do hate those dual ambulance sirens....

Those sirens add to the suspense! I live in Allen, and our sirens are sooo much quieter. I can hear Plano sirens and sometimes even Dallas sirens

I live in East Texas...I feel your pain of tornado warnings/watches. Just this Christmas a tornado was spotted a few miles west from my city. Sometimes I wished I lived somewhere else. Those clouds always creep me out. That's why I dread spring...

I love that a tornado happens all windy, rainy, and stormy this dude sits here xD

@Thomas Grimm what type of sirens are those like WHELENs 4000,B-Link,vortex series or FS like 2001's Modulators etc if possible video a test of the siren itself like This is a tornado warning by WhiskeyFoxtrotTango

Good thing they didn’t sound the sirens sooner. It wouldn’t make sense to give people more time to figure out what to do.

I remember that tornado.That was about a year after me and my mom,dad and brother moved to fortworth.That was the scariest day of my life.I will never forget the day it happend

The fact of the matter is you can either go hide in your bathroom for hours or you can go outside and see for yourself. MOST of the time tornados dont just sneak up on you so you can see them miles away before they are anywhere near you. I say most of the time cause sometimes they are rain wrapped and in this case I dont know if it was the camera but it seemed pretty dark and sketchy so hats off to you brother for hanging in there and giving us the great vid!!!

Cool video! I've seen a green sky like that over here in Pearland a couple times.

eerie video! Great job!

is this at night? they are rare to have at night right? I've never seen one I live in a place that lately has had these scares and have had a couple touch downs but nothing to close to home. Mostly a very hilly place and rare to have them but a lot of warnings lately, hopes to be over soon.

The sirens are on Attack Mode (used for air raids, fire calls and tornado emergencies when a tornado touches down in the city).

i had a creepy tornado storm once, it was a school day and was pretty windy and when it was time to go pick up my brother it was getting cloudy quick and i was like "its like so windy today, mom". and she said "we were in a tornado watch all this time and is supposed to get worse very soon". i was a little freaked out but when the storm hit it said that it was severe and there lightning strikes everywhere and after the storm it went to sunny pretty fast which told me something worse was gonna happen and it happened another severe t-storm came and brought hail that it stopped and eveything was back to normal as if that is what i thought, that night there was a tornado warning for the county of bluegrass and that was the closses town to mine and it got pretty bad than we had the tornado but we did not go to any shelter we watched it and was awesome and no damage besides a few branches from that storm. my county was Muscatine, IOWA

0:02 BEAUTIFUL WALL CLOUD!

I've been through that kind of storm in Columbia City, Indiana. I had to go to the library with my 13(Now 14) year old sister, and 7 year old cousin. We were in a Severe Thunderstorm Warning but I only knew that because of my aunt. Just being inside a library that's mostly glass was scary and like the sky was pitch black. The sky went from like grey to almost charcoal black. When I saw the supercell forming I nearly burst into tears. But with me being 11 at the time I knew if I broke down by my 7 yr old cousin he would freak out. The sky was green and I immediately thought about a tornado. We had no Tornado Watch or Warning. The only cool thing was the rain it sort of calmed me down.

Oh God this happened one year after me my mom and dad and brother moved from California to Texas. we moved fairly close by fort Worth and watching this gives me the chills

Was that a big tornado in front of you when you were filming the storm or was it a cloud?

that was right before he shut off the video you could hear the WIND PICK UP ....that tornado was coming right for that town!

@y0ureviltwin what kind of siren is it?? Also nice Attack or Wail tone

My gosh, I remember this storm! I was in fifth grade and lived in Keller at the time. I was SCARED YELLOW, especially being (originally) from Wisconsin and not used to awful storms. Let's just say I've been back in WI since I was 18. (I'm 25 going on 26 now.)

I live in Milwaukee and to me that siren just sounds like a bunch of ambulances or fire trucks or something. I'm surprised there isn't a national standard so people know what is going on no matter what city they are in. Up here a tornado siren sounds like a long air raid siren.

I hope we never get anymore tornadoes, ever. I live in Houston, we had our share of tornadoes & we have no tornado sirens. Last time a tornado went through here was in November 1992 in Katy in the west, passed up Pearland, & Channelview 2 the east. Dallas/Ft. Worth metroplex is only 4 hours away by car.

Yikes! I live in Fort Worth now and correct me if I'm wrong but they tend to get more tornadoes than in Dallas, right?

Was that a big tornado right there when the sirens started to go off as you were filming or was that a cloud?

Its so paradoxical that somethinge like this can be scary and fascinating at the same time

whatever the sirens used in your area are, that particular tone frightens me than any other. I guess because its also the ones used near me!

I fly into Dallas Fort Worth Texas to see my grandparents in the summer, and had never experienced a tornado when I have been there.

What kind of sirens were heard in this video?

Sirens in Wisconsin sure do sound a lot different!!!

when the sky turns green thats when ya know a tornada is comin lol

Most homes in North Texas do not have storm cellars or storm shelters.

Please reply. When was this? I use to live in Texas Fort Worth. This almost happened to me...

Thanks & V good job with the video considering the situation, As far as I'm concerned, there is Nothing scarier and No place I'd rather be than that exact situation. The siren makes every tornado warning just that much better whether in person or on video.

What time of day was this?

that sound is going to leave me scarred for awhile

Terrifying but good. Great twister sirens though!!

I saw a green sky a few times and had some tornado warnings. But where I live we don't really get any tornadoes. A few times we had wind storms that came up to 100 winds and had power outages!

tornado siren = Scariest noise i've ever heard, I'm from the UK, but I was walking my dog once, and I think they were testing the flood sirens because the area I live in is like a 15 minute walk away from the sea, but yeah, I was scared like hell, I have always hated the sound of these sirens purely because it signifies that shits about to go down...

I'll never forget the day I first heard this when I was really young.

I can´t imagine what it must be like to live in an Area where you have to be afraid all the time. I am so glad that we don´t have Tornados or Earthquakes or whatever where I live.

Did a tornado still develop in your area?

I live in NY. I really wanna see a tornado already! Obv I don't want it to be anywhere it can hurt anybody, but it must be awesome :O

You guys in North Texas mainly around the Dallas/Ft. Worth metroplex have tornado sirens, y'all are soo lucky where some parts of Texas don't have tornado sirens. In Houston there are no tornado sirens, even though it's rare doesn't mean it won't happen. 1 ef-2 tornado went through the suburb of Katy & another tornado an ef-4 went through the east side of town in Channelview. & I think another 1 went through Aldine, which is in the north side of Houston a long time ago.

That is one mean looking supercell! Only seen shit like this where i'm at in Phoenix AZ maybe twice in my entire life.

i live in texas 2 just moved here and how do u guys put up with this....? just wondering..

Sweet, a Whelen WPS-4004!! How many of those do you have around here?

Where was this at... Like what neighbor hood, or side of fort worth?

Was it day or night when it happened?

Everybody gangsta until the street lights are on

A hard tornado came in 2011 here in Texas. I was in school, and we HAD to take cover, nothing happened, only lights flickering. The tornado was about 3 or 4 blocks away. We saw green skies, i was scared :T

Agreed And if you those emergency vehicle sirens when a tornado warned storm is very close,you know something big is nearby

idk why the sirens are always more terrifying than the storms 😅

Why are the sirens going Hi-Lo? Usually that’s reserved for nuclear attack, nothing else. From what I’ve seen and heard, during a tornado warning, the sirens do the “alert” tone, usually one steady tone for 2 minutes. Maybe Ft. Worth was different back then?

What exactly means "when the sirens go off" are there any codes for it?

Wow! What a video! How far is that town of Aledo from where you shot this video? The skies looked pretty menacing indeed! Did it ever come near where you were? Pretty scary stuff!

when the sky turns green its never a good sign if anyone of you have seen the movie Twister when Dusty asks Bill what hes doing Bill looks at the sky and says "Going green" which meant he knew the tornado was coming

@y0ureviltwin what type of sirens are those like WHELENs 4000,B-Link,vortex series or FS like 2001's Modulators etc if possible video a test of the siren itself like This is a tornado warning by WhiskeyFoxtrotTango

Man those clouds are scary, here in South Florida we get bad storms but not like that sometimes there is a lot of lightning and very dark clouds in the spring and summer months.

IF YOU WANT TO KNOW WHAT SIREN IS NEAR YOU, its a whelen vortex r4

I filmed this using an old fuji digital camera, I had it on a tripod dvd that's what you hear clicking

Wow! I've never seen the sky turn green before...didn't know that could happen!

this is the type of weather that makes me shit my pants when i hear the sirens go off

Were those Whelen Vortex R-4 sirens going off?

how often does fort worth get tornadoes and how big are they?

that siren just brings many memories of storms like theese

Do you live in a safe area where the homes are in a good location?

Yup . The sirens are worse than the tornadoes . Today the radio is nothing but tornado warnings . I'm about 12 miles north of a tornado that hit 5 minutes ago in Tarrant county , TX .

This is eerie as hell

I believe those sirens are whelens in attack/wail mode. Some states use attack instead of alert for tornadoes

@halomaniac07 No, it was just a rotating wall cloud when it got near my home, but a few miles west it did touch down.

those tornado sirens scare the hell out of me

What Time Was This At

this siren is scary but i love it ^^

I’d be scared as hell if that happened during the nighttime...

Holy crap, you guys have it good, where I live the tornado siren is the same siren that they use for air raids! And it's way scarier than this.
