Friday: 5-10 cm new snow with freezing levels around 900 m. Strong southwesterly winds.Saturday: Around 5 cm new snow with freezing levels around 700 m. Moderate southerly winds.Sunday: Mostly dry with some sunny breaks. Freezing levels around 600 m. Light northwesterly winds.

Avalanche Summary

There was a natural avalanche cycle on Sunday. So far this week, no activity has been reported, although there are not many observers out there right now. Small wind slabs are the most likely type of avalanche during over the next few days.

Snowpack Summary

Approximately 30-40 cm new snow now sits on top of a rain crust that formed during the recent wet weather. The crust is reported to be thick (15 cm) below treeline and thin (2 cm) in the alpine. Strong winds have blown snow around in exposed areas creating drifts and scoured areas. Treeline snow depths are approximately 90 cm throughout the region.

Problems

Wind Slabs

Small wind slabs are possible in steep terrain behind ridge lines. On steep slopes, the new snow may not bond well to the underlying crust.

Use increased caution in lee areas. Recent snowfall and wind loading have created wind slabs.Use ridges or ribs to avoid pockets of wind loaded snow.

Aspects: North, North East, East, South East, South.
