It was because there was a thunderstorm warning for the streamer's area in Texas (Tarrant County, IIRC), and since Discovery Family is not a broadcast channel, but a cable channel, it was that streamer's television provider that broadcast the warning (and - this is speculation - the reason that it sounded off could have been because that provider had their EAS equipment configured incorrectly).

But yeah, it is a regional thing - the Wikipedia page has more details and specifics.

Speaking from personal experience, the EAS on my television provider (FiOS by Frontier Communications) looks different - for one, it interrupts the video as well as the audio (so instead of having the text scrolling along at the top of the screen with the video still playing underneath, it has the text scroll at the top of the screen while the background cuts to a gray screen with white text, telling what the general alert is about, whether it's a severe weather alert, or just a required test), and also the audio setup is configured correctly, because it sounds how it's supposed to.

I also remember getting alerts for flash flooding (especially during an El Niño winter like the past one, where we get way more rain than usual), and I swear I've also gotten alerted for wildfires as well (though those aren't listed as an event on the EAS Wikipedia page - could be that because those are more of a problem here in Southern California they added those, or my memory's playing tricks on me), even if the part of Orange County I'm in isn't particularly fire prone.
