Ryan Hall is an American weather YouTuber known for long live streams tracking tornadoes, hurricanes and severe storms across the United States. His broadcasts use alert tones to mark urgent National Weather Service warnings, including the rare tornado emergency designation for confirmed, life threatening tornadoes. The clip labelled TOR-EM-SIREN captures that emergency tone in isolation, lasting about eight seconds. As his streams were clipped on social media, the tone moved beyond weather coverage into meme edits, where it now signals any exaggerated emergency or incoming disaster.
