Points saillants

Natural avalanche activity is decreasing, but human-triggering is still a very real possibility. Increased winds will also add to the prevalence of wind slabs. Conservative route selection is in order.

Wind slab development is ongoing as moderate westerly winds redistribute the low density snow. Lee and cross-loaded features at and above treeline are areas of concern.

Recent natural avalanche activity is stepping down to the November rain crust.

Weather Forecast

Alpine temperatures should reach -15 celsius under a mix of sun and cloud. Winds will increase to 35km/h from the West. No precipitation is in the immediate forecast.

Avalanche Summary

The avalanche cycle continued today, but natural activity is tapering off. Numerous loose dry and slab avalanches up to size 2.0 were observed today. Generally speaking the slab avalanches are not propagating widely, but some of the slabs are stepping down to the November rain crust.

Snowpack Summary

Recent storm snow of 50 to 70cm has settled rapidly in the past 24hrs. Increased winds are now redistributing this low density snow and forming more extensive wind slabs in Alpine and Treeline terrain. The November rain crust remains a prominent feature near the base of the snowpack.
