Timeline of a Freak Mountain Storm: When High Elevation Near Salt Lake City Turned Treacherous
The morning began with deceptively calm conditions across the metro basin. By mid-day, radar stations operated by the National Weather Service in Salt Lake City detected a rapid influx of mid-level instability. Moisture tracks had worked their way across central Utah, and as temperatures peaked in the low 80s down in the valley, the mountain slopes became thermal engines.
Around 2:15 PM, outdoor recreationists hiking alpine trails above 7,000 feet reported sudden, unseasonal chill. The barometric pressure dropped sharply. Clouds began condensing rapidly against the slopes. By 3:30 PM, spotters and mobile video units captured rotation descending from a low cloud deck nestled directly against the mountainside. The Weather Channel confirmed that the twister touched ground at roughly 7,500 feet, tearing through alpine timber and scattering scree before dissipating against higher terrain.
