Eight people were caught by the slides, but no one was injured or killed.
The Utah Avalanche Center reported Sunday that humans triggered 13 avalanches on a “sensitive” Saturday, a meteorologist said.
Trent Meisenheimer, a forecaster for the Utah Avalanche Center, said, “This time of year we get a lot of warm-ups where the surfaces melt and then it freezes back and becomes slippery. And in spring, coupled with some fresh snow and strong winds, that’s sometimes enough.”
When asked whether all of these avalanches had killed or injured, Meisenheimer said “fortunately no,” but eight people were caught and carried down the slides.
According to the Utah Avalanche Center, there were nine man-made avalanches in the Salt Lake City area, three in the Logan area and one in the Provo area as of Saturday.
The center said Sunday that avalanche danger was moderate in the Salt Lake City, Logan, Ogden, the Uintas and Provo area. It also warns people to stay away from roof edges where roof avalanches could be a possibility. Last week a 50-year-old man was killed by a suspected roof avalanche in Brighton.
