In sintesi

Heightened avalanche conditions exist and there is MODERATE danger for avalanches in the Logan area backcountry today. It is possible to trigger soft slab, wind slab, loose dry and/or wet snow avalanches.

Evaluate the snow and terrain carefully.

    With several human triggered avalanches reported yesterday and the new snow failing to stabilize quickly in some areas, it might still be possible to trigger a soft slab or loose snow avalanche today on steep slopes. This problem exists mainly at high elevations as well as east and north facing mid elevations.

    It might also be possible to trigger a soft wind slab avalanche on high elevation east facing leeward slopes where light to moderate winds have deposited snow. Watch for cracking as a sign of instability.

    Evaluate terrain carefully and continue to practice safe travel protocols to minimize your risk. Staying on slopes less than 30 degrees is the best way to avoid this problem.

    Despite the cool mountain temperatures, the high angle of the late-March sun will affect the snow today. Even yesterday the new snow was dampening quickly on slopes hit by direct sun. If you notice the snow feeling dense and moist or you see signs of instability like roller balls or pinwheels, move to lower angle terrain or to a shadier aspect.

Special Announcement

UAC operating schedule - We will continue issuing regular avalanche forecasts into mid April.

Spring Awareness Campaign - The UAC counts on donations from the backcountry community. We know these are uncertain times and any donation during our awareness campaign will help us continue providing avalanche forecasting and education.

CDC Guidelines - Even in the backcountry and in parking lots, please follow CDC guidelines like limiting group size and keeping a distance of at least 6 feet from other people to protect yourself and others. Read the guidelines HERE.

Taking risks - Be extra conservative to avoid the risk of accidents which can stress the capacity of our medical system.

Skiing and riding at closed ski resorts - Some resorts allow access now and some do not. Please check HERE for the latest info on ski area access.

New to the backcountry (including riding at closed resorts) - Watch the award-winning, 15 minute Know Before You Go video, or take the 5-part, free online-learning series.

Recent Activity

Several human-triggered avalanches were reported yesterday. Most were about 10-15 inches deep, 50-80 feet wide and ran between 300-500 vertical feet. These were mostly soft slab and wind slab avalanches of new snow on east facing high elevation slopes with the exception of one on a north facing mid elevation slope.

In some areas the new snow stabilized quickly while on east facing slopes the new snow was still sensitive and reactive yesterday morning in the Central Bear River Range.

We also noticed evidence of widespread natural loose avalanches of new snow on steep slopes that occurred Tuesday night during the height of the storm.
