There is a lot of uncertainty with snowfall amounts through the period. There is good potential for amounts to exceed what is forecast in parts of the region. If that is the case, expect danger ratings to be higher than indicated.

Avalanche Summary
No new avalanches have been reported. The main concern continues to be the possibility of triggering the weak faceted layers deeper in the snowpack.
Snowpack Summary
Taking regional variations into consideration, 5-10cm of new snow may overlay wind-affected surfaces at higher elevations. Below 1500 metres you may find an isolated thin breakable rain crust about 1 cm thick. The snowpack is quite variable throughout the region. In deeper areas, the snowpack appears to be well settled with isolated concerns about the mid-December facet layer buried 50-100 cm deep. In shallow snowpack areas and lower elevations, the snowpack is weak and faceted. For instance, in the Elk Valley north area near Crown Mountain last week the height of snow was 90 cm with foot penetration of 80 cm; or almost to ground. In these areas, the wind has formed isolated hard slabs above weak facets and created the potential for large persistent slab avalanches.
