In some areas, unstable snow persists on isolated terrain features. Skier-triggered wind slabs remain possible. Carefully assess the consequences of a release.
Small wind slabs (10 to 30 cm thick) are reactive in tests and to skier triggering. These wind slabs have been observed mid-slope and are resting on a weak layer of large snowflakes. These small wind slabs could trigger underlying wind slabs.
No new avalanches reported or observed.

Recent strong winds have significantly redistributed the snow in alpine terrain and at treeline. Many aspects are scoured. Below 600 m elevation, a friable melt-freeze crust is present at a depth of approximately 10 to 20 cm.
The upper and mid-snowpack is stabilizing and becoming progressively denser. At the base of the snowpack, a combination of crusts and faceted grains extends down to the ground.
The average snowpack depth at mid-mountain is approximately 120 cm.
Cold temperatures will remain firmly in place this week.
