Highlights

Areas with MODERATE danger may exist, and people could trigger small wind slab avalanches on slopes steeper than 30 degrees in drifted upper-elevation terrain. Otherwise, the avalanchedanger is LOW, and avalanches are unlikely.

    People might trigger small avalanches of wind-drifted snow where wind slabs recently formed on preexisting weak surface snow in exposed upper-elevation terrain.

    • Avoid and stay out from under stiffer pockets of recently drifted snow on steep slopes.
    • Wind slabs may have formed or have been cross-loaded in and around terrain features like mid-slope roll-overs, gullies, under cliff bands, or sub-ridges.
    • Wind slabs are often chalky, rounded, and smooth, and they can sound hollow, like a drum.

Special Announcement

***Join us for a Backcountry 101 for snowmobilers on January 28 and 29. This life-saving course is designed for snowmobilers and snow bikers taking their first on-snow avalanche class or looking to refresh previous training. For more information and to sign up, click here.

Snow and Weather

Overnight winds increased a notch, veering from the west-southwest. Drifting may have created pockets of unstable snow in exposed upper elevation terrain, primarily on slopes facing the eastern half of the compass, and people could trigger small avalanches of wind-drifted snow today. It is still possible to find soft recrystallized snow or "loud powder" on select lower-angle sheltered slopes; however, untracked snow surface conditions are quite variable across the zone, and crusts of varying thickness are found in sunny terrain. Total snow depths are four to five feet in upper elevations, but in low and mid-elevations, they are exceptionally thin, creating hazardous travel conditions due to rocks, downed trees, and barely covered branches.

This morning at the UAC Card Canyon weather station at 8700 feet, it's a chilly 9°F, and there is 41.5 inches of total snow. The Tony Grove Snotel at 8400 feet reports 16°F and 2 inches of new snow from yesterday, with 55 inches of total snow. On Logan Peak at 9700 feet, winds are blowing from the west-southwest at 36 mph and gusting to 45 mph. It's 8°F (and the wind chill is -15°F) on Paris Peak at 9500 feet, and the wind is blowing from the southwest at 30 mph and gusting to 40 mph.

It will be cold in the mountains again today, with 8500' highs around 23° F and winds blowing from the west-southwest at 10 - 15 mph (wind chill in upper-elevation, exposed terrain will be around -8°F). The weather is expected to remain cold, dry, and somewhat unsettled through Thursday, which should help limit valley haze. There's faint hope for a few snowflakes in the Bear River Range on Wednesday afternoon and evening.

Additional Info

A layer of small near-surface facets, pictured above, is just one of the many weak surface layers we are currently tracking. Once buried, this will likely become a problem persistent weak layer.

Use safe travel practices: travel with a partner, and cross or ride steep slopes one at a time while the rest of your group watches from a safe spot.
