Kernpunkte

A weak layer continues to linger over the holiday season. A conservative approach to your terrain selection is the best way to manage it. See the forecaster's blog here, which describes this persistent problem.

    A weak layer buried around 50 to 100 cm is still the main concern. Although avalanche activity has been quiet for the past week, the widespread nature of the layer and snowpack test results suggest that it is still a layer to be concerned about.

Avalanche Summary

No new avalanches were observed on Wednesday.

Snowpack Summary

Around 5 to 10 cm of snow sits on a thin sun crust on southerly aspects and small feathery surface hoar in sheltered areas.Beneath this, around 50 to 100 cm of snow is poorly bonded to a rain crust and a weak layer of feathery surface hoar and sugary facets. Although there has not been a reported avalanche on this layer for about a week, snowpack test results tell us that it is still possible to trigger. It is best to remain conservative and travel cautiously with this layer in the snowpack.The lower snowpack is well-settled.
