Points saillants

Most slopes have a LOW avalanche danger. You may be able to trigger a small slab in isolated areas where recent wind drifted snow to form a cohesive slab or loose dry avalanches in steep, sheltered locations.

Avalanche danger will rise through the weekend.

    Early-season snowfall from October and November melted off in most locations but lingered on slopes facing W-N-E above 8500 feet and turned into a layer of facets.

    The Southern Wasatch received less snow than the Northern and Central Wasatch, and we haven't seen the same avalanche activity as those areas have. That said, the same faceted base exists in the Southern Wasatch. For today, it's unlikely you would trigger an avalanche that breaks on the faceted layer near the ground; the exception would be in isolated areas where recent wind drifted snow into a cohesive slab.

    As we look into the weekend, expect the avalanche size to grow and the likelihood to increase.

Snow and Weather

This morning, temperatures are cold. Trailheads are in 10˚-15° Fahrenheit, and upper elevations are in the single digits. Winds at blowing from the NW at 5-15 mph at 9000 feet and 10-20 mph at upper elevations. Yesterday, some favored locations saw an inch or two of snow, but most locations only received a trace.

Today, skies will be mostly clear with some low clouds obscuring peaks early in the morning that should burn off by late morning. Temperatures rise into the low to mid 20˚s Fahrenheit. Winds will be from the WNW at 9000 feet, will be light 5-10 mph, and 20-30 mph along the upper elevation ridgelines. We may see an increase in winds late this afternoon as the storm approaches from the northwest.

This weekend, a significant winter storm moves in late tonight through the weekend with 1 to 2 feet of snow expected. The wet and windy storm favors Northern Utah and locations with a WNW flow. Expect the rain/snow line to rise through Saturday morning to ~7500 feet before the cold front arrives Saturday afternoon. Avalanche danger will quickly rise as snow accumulates.

Our partners are the National Weather Service in SLC have issued a Winter Storm Watch for the Wastach and Western Uinta Mountains from late tonight through late Saturday Night in anticipation of a prolonged period of heavy snowfall and difficult travel conditions.
