    This layer is a concern in isolated areas loaded by wind. These slabs sit on a weak facetted base. There has been no recent natural avalanches on this layer but it still may be triggered by skiers or climbers.

Weather Forecast

Light flurries and moderate W winds are forecasted for the next few days.  There is very little snow left for transport so the hazard will not be significantly affected.  Temperatures will become warmer through the week and by Saturday alpine temperatures will be in the -7C range.

Snowpack Summary

There is 50-70 cm of snow at tree line which is generally weak, and facetted, however in some areas the mid-pack is supportive enough to allow some tentative turns. Some fresh wind slabs exist in lee alpine terrain which may be reactive to skier triggering. The October crust is 10-20 cm from ground and producing mod-hard results with comp. test.

Avalanche Summary

No new avalanche activity observed in the last several days.
