Every Dallas Weather Siren Hacked on Friday To Go Off At Once - Sensationalist Headlines

[QUOTE=michaeldim;52087252]When you hear sirens, you're supposed to turn on a TV/radio to figure out what's going on, you don't automatically leave the house.[/QUOTE] Also in the midwest, it means get the fuck [i]inside[/i] because tornado danger is imminent. Evacuating is actually the [i]worst[/i] possible idea. But then again, they are set to the attack signal, rather than the weather one, which would be a bit disconcerting. Either way, turning on the local media is the correct thing to do, not evacuating.

[QUOTE=Snowmew;52087491]The electric ones can play voices and different tones and shit like that which would be more helpful.[/QUOTE] Ah! You think it would be a defense project then rather than a mayor? Oh, Well.

But then again, they are set to the attack signal, rather than the weather one, which would be a bit disconcerting.[/QUOTE] Best thing you can do is get into a cellar/basement or in a central area of a building. If you're caught outside take cover in a ditch or any low-lying areas and keep your head down. Last place you want to be is in a car that can be picked up and thrown. I've also heard that panic rooms can be good shelters as well.

[QUOTE=Bbarnes005;52087514]Best thing you can do is get into a cellar/basement. I've also heard that panic rooms can be good shelters as well.[/QUOTE] Cellar/basement and barring that, an interior room of the house without windows like a bathroom. Never a trailer home though. Although less than optimal as your exposed, a low ditch (not an overpass or culvert) is the best place outside. It reduces your surface area from wind and debris.

Also don't try to outrun a tornado in a car as well because you'll most likely lose as most tornadoes move extremely fast.

Some use Hi-low even. Or whatever the fuck this is: [media]https://www.youtube.com/watch?v=Yy_oX6SURRE&t=30s[/media]

[QUOTE=meppers;52085954]I live in dallas. the weather was clear on friday. if you hear an alarm you check the weather on your phone. then you go back to bed when you see no green blobs on the radar[/QUOTE] Not everyone has the convenience of a smartphone or a weather app or a data plan.

The old Thunderbolt sirens apparently could be equipped with it and it sounds rad on a mechanical one. [video=youtube;V-FWTQYzH_4]https://www.youtube.com/watch?v=V-FWTQYzH_4[/video]

There is literally a fan community for everything.

I get where papkee is coming from, there's literally no security on this so anyone could do it and as such it wouldn't refer to the colloquial definition of hacking, but by dictionary definition it definitely still counts as hacking.

I always thought that siren was for warning nuclear attacks. [QUOTE=OvB;52086077]I didn't think I needed to be explicitly specific.[/QUOTE] Welcome to Facepunch.
