    Variable wind slabs are prevalent , and will be most likely triggered from shallow snowpack areas propagating into thicker snowpack areas on facets.

Weather Forecast

5-10 cm possible by Thursday night with mod-strong NW winds and slightly cooling alpine temperatures.

Snowpack Summary

Recent strong winds have created widespread wind effect in the alpine. Windward slopes are scoured and hard and soft slabs that are possible to trigger exist elsewhere. In shallow snowpack areas the mid-pack has facetted out and become weaker. Below 2200 m surface hoar exists in some locations and produces moderate results with comp. tests.

Avalanche Summary

No new natural activity today. Hard windslabs to size 2 have been skier triggered within the last few days in the alpine.
