Generally stable conditions exist, and triggering an avalanche is unlikely. However, even a small avalanche can have major consequences. Always use safe travel practices, such as exposing only one person at a time to avalanche terrain.

Low danger doesn't mean no danger. Small avalanches can still happen, and will have serious consequences in extreme terrain like couloirs or large exposed faces.

Always be on the lookout for signs of instability, such as recent avalanches, cracking, and collapsing. Take the time to assess each slope you plan to ride. If you see any signs of instability, or find obvious strong snow over weak snow, choose slopes less than 30 degrees in angle. Ski and ride one at a time, and regroup out of avalanche terrain.

Temperatures dropped overnight as cold air moved in over the Continental Divide. In some parts of our region, these cold temperatures are accompanied by gusty east winds. Despite the wind, we don't expect much new wind slab development. Even though wind speeds may be strong enough to move snow, there is limited snow available for transport. The wind can't create a slab without soft snow to entrain and deposit. At the highest elevations (above roughly 8000 feet), which escaped last week’s high freezing levels, you may find small new drifts.

You’ll notice that we’ve removed the persistent slab avalanche problem. While triggering a persistent slab avalanche is very unlikely, weak layers are still present in the snowpack. In isolated high-elevation terrain, you may find crusts and/or facets buried 1-2 feet deep. Dig down and look for these layers before committing to your line. If you find them, you should ski or ride elsewhere.

Surface hoar exists on the snow surface in many places. If this layer survives to be buried, it could create a problem down the road. If you get out in the mountains, please let us know where you find surface hoar. This will help us with future forecasts.

Thank you for all the great observations recently. They help us create better forecasts, and we truly appreciate them. Please keep submitting! 

Avalanche education is a lifelong journey built on developing sound judgment, gaining experience, and applying repeatable decision-making systems in the backcountry. Our American Avalanche Association (A3) recognized Level 1, Rescue, and Level 2 courses are offered throughout the winter and help you travel smarter in avalanche terrain.
