Investigate the bond of the recent snow and be most suspect in open areas, around ridges, or in loaded start zones.
On Friday, skiers reported triggering sluffing with the fresh snow. Further west, Whistler-Blackcomb avalanche control reported reactive storm slabs to size 1.
No new avalanches have been reported recently.

20-40 cm snowfall accumulated by Saturday with strong southwesterly wind, deeply loading lee features. 30-60 cm of recent and settling snow covers the Dec 30 crust; this crust is more prominent at treeline and below, and varies in thickness and strength across the forecast area.
The Dec 20 crust is now down 50-100 cm, covered with facets and isolated surface hoar. This layer is trending dormant with the last avalanches occurring on Dec 31st (in areas south and west of Pemberton)

Terrain and Travel Advice
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- The new snow may require another day to settle and stabilize.
- Investigate the bond of the recent snow before committing to your line.
Snow fell with strong southwesterly wind, and quickly developed reactive slabs. Wind transitions northerly, suspect areas will be around ridges and (previously) wind-affected terrain, and in pockets with deep depositions.
