After a dry snow season so far, avalanche danger across Utah's backcountry is expected to skyrocket this weekend. “These are the types of avalanches that catch, carry and kill people,” said avalanche forecaster Trent Meisenheimer.

A man rescued his brother from a “large avalanche” he triggered while the pair were snowmobiling in Utah on Wednesday, authorities said.

“Because the new snow will overload weak, pre-existing faceted snow, avalanches may be triggered from hundreds of feet away, making for particularly tricky and dangerous conditions,” according to the center.
