A poor snowpack structure exists on shady aspects above roughly 7500-8000'. Yesterday, backcountry observers noted cracking and collapsing associated with this layering but did not trigger any avalanches. Derek DeBruin's snowpit profile is below. At this point, the best strategy will be to avoid steep terrain that harbors this weak unstable snow structure. Remember that you can trigger these avalanches from a distance.

Recent Activity

Ski area control teams yesterday remotely triggered some wind slabs as well as loose new snow avalanches.

Snow and Weather

Skies are clear.

Temperatures are in the teens. Winds are generally light from the west.

An additional 3-4" of low density snow fell yesterday, pushing storm totals to 20-30" since late Tuesday.

For today, we'll see clear skies, light wind and mountain temperatures in the 20s.

We'll have a bit of a break before the next series of storms barrel through mid/late week.
