SALT LAKE CITY -- A scattering of avalanches in the Wasatch Front mountains over the weekend may be an opening act for more slides this week, Utah officials said Monday.
The Utah Avalanche Center reported three slides were recorded Saturday and five Sunday, including one that carried a skier about 150 feet down a mountain.
The center said no one was injured in that slide, which occurred near the top of Little Cottonwood Canyon on Sunday afternoon.
That avalanche was 1 1/2 to 2 feet deep and about 60 feet wide, forecaster Evelyn Lees said.
Forecaster Drew Hardesty told the Deseret News that fresh snow fell over the weekend on top of weak, older snow, which makes it likely that more avalanches will occur.
He called it the "perfect recipe" for avalanche accidents.
"It's probably a canary in a coal mine," he said of the weekend avalanches. "I would be shocked if we were not talking again later."
There's a risk for more slides through the middle of the week, particularly above 9,000 feet in elevation, officials said.
Hardesty said anyone on the mountains should keep in mind that slides can be triggered remotely by someone or something.
"You can trigger them while not even being on the slope," he said. "You can trigger them from below, or adjacent to the slope or above."
Forecasters recommend that anyone hitting the slopes stay on areas that are less than 35 degrees in steepness, with nothing steeper above them.
The Avalanche Center is a partnership between the U.S. Forest Service and other state and local agencies.
