Cold day, snow on the way!

Posted Wednesday, December 29th, 2021 by Tory Peters

TL;DR: The Wasatch remains cold and will get windier moving into tonight, with more precipitation on the way tonight and tomorrow. The New Year will bring a lull in weather, but offer a great opportunity to spend some time in the sun. Don’t be fooled by the lull in the storm, avalanche danger is still considerable with the potential for fatal avalanches, so please be cautious if you’re headed into the backcountry and head to The Utah Avalanche Center’s website for a full forecast and breakdown of the current avalanche problems.
