    Caution in thinner snowpack areas where you may be able to wake up this layer. 

Confidence

Moderate - Due to the number of field observations on Thursday

Weather Forecast

Cloudy with trace of new snow overnight.  Winds continue out of the north and are light.  Look at Mountain weather services also available at Avalanche.ca

Avalanche Summary

No new activity in the past 24hrs. 

Snowpack Summary

The recent storm snow continues to settle.  Some windslabs were observed in Alpine areas up to 25cm thick but these were not that widespread at this time.  The Dec 15th interface is down 30-40cm but a lack of a cohesive slab is preventing widespread activity on this layer.  The key thing to be aware of is the windslabs that are developing and the potential for triggering as you move into more wind affected areas.
