Ryan Hall, known online as Ryan Hall Y'all, built a large audience livestreaming severe weather and explaining National Weather Service alerts in plain language. A Particularly Dangerous Situation warning is reserved for confirmed, exceptionally dangerous tornadoes, so his streams treat that label with extra urgency. Clips and alert tones from those broadcasts began circulating on soundboards, where the warning sound escaped its original context. It is now reused far from real storms, as a shorthand for maximum danger in memes, gaming edits and reaction videos.
