    A couple of week layers from earlier in the month are lurking in the top meter of the snow pack. Continued loading and settlement of the overlying snow may increase the likelihood of triggering an avalanche one of these layer.

    Recent snow combined with suspected strong winds are likely loading lee features. Watch for wind slabs.

Snowpack Summary

There is significant variation in snow depths across the region. In the Smithers area the ski hill is reporting an 111 cm base with the Ashman trailer is around the same. Treeline depths vary between 100 - 200 cm.The region has received up to 10cm of snow in the last 24 hours. Between 30 and 80cm of snow now rests upon a crust that extend up to treeline and possibly beyond. This interface has been popping under easy loads in snowpack tests.We don't have great wind stations in the region, but the coast saw a lot of strong wind during the last storm & I suspect this region was similarly hammered, forming windslabs in the alpine and at treeline.Deeper in the snow pack a layer of facets/surface hoar formed during the early December cold/dry spell can be found in the top 100cm in the Ashman . The mid and lower snowpack is still structurally weak and faceted. Depth hoar and an early season crust exist near the ground.
