    Last weeks storm snow has settled and in many areas above 2200 m is sitting on the October melt/freeze crust. We are no longer seeing natural avalanche activity on this layer but human triggering is still possible.

Weather Forecast

Mixed sun and cloud with moderate westerly winds for Tuesday. Sunny day on Wednesday with freezing levels rising to 1800 metres and then a slight cooling trend for the end of the week. We may see some light snowfall by Friday.

Snowpack Summary

Eighty to 100cm of snow exists at treeline locations. The mid pack is slowly becoming more supportive and travel is becoming easier. The October 27 crust is still present 10-15 cm from the ground in many locations above 2200 metres. This crust was a significant sliding layer in last weeks avalanche cycle and should be monitored carefully.

Avalanche Summary

No avalanche activity was observed or reported today.
