In sintesi

The recent snow might not bond well. In areas that recieved more than 20 cm small storm slabs could be triggered.

    Rider triggerable storm slabs may still be found in areas where recent snow overlies surface hoar or a smooth crust. In areas that recieved less than 20 cm of new snow a dry loose avalanche problem is more likely.

Avalanche Summary

Numerous wet loose avalanches were reported during the sunny period earlier this week.

We expect that in localized areas that recently received more than 20 cm of new snow rider triggerable storm slabs could be found.

Snowpack Summary

Up to 20 cm of new snow overlies a crust on all terrain except north facing slopes treeline and above. On these high northerly slopes new snow overlies facets and surface hoar to mountain tops.

The mid pack is generally well settled.

The lower snowpack includes a layer of weak sugary facets near the ground. These facets are slowly gaining strength and no recent avalanches have been reported on this layer. However, we continue to track the layer and watch for any signs of it becoming active.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
