Avalanche Summary

Preliminary reports from Sunday indicate small (size 1) wind slabs were triggered by riders on all aspects in alpine terrain. Activity on Saturday was limited to loose dry sluffing in steep terrain.

Snowpack Summary

Recent wind has formed isolated pockets of slabs in exposed terrain, while sheltered areas have cold low density snow. The top 20 to 40 cm of the snowpack consists of low density snow that is gradually settling onto old hard surfaces including crusts and wind-packed snow. Low-density snow may sluff easily on these hard surfaces. The lower snowpack is strong and settled.

Avalanche Problems

Wind Slabs

Northeast winds are forming fresh slabs in exposed terrain, while pockets of old wind slabs can be found on all aspects.

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
