Avalanche Report
Avalanche Advisory For Wednesday, December 17, 2025 - 7:19am
Salt Lake Area Mountains
Bottom Line
Avalanche danger will rise to MODERATE by the afternoon in mid and upper-elevation terrain IF the windy and wet storm delivers. Be most suspect of northerly slopes at upper and mid-elevations, where the wind is building slabs of new snow over our persistent weak layer (PWL) that can break 1-2 feet deep. New snow will also be loading on slick, icy crusts where it can run farther and faster than expected on all aspects. Avalanche danger is LOW as of early this morning before the arrival of the storm.
