⚠️Dangerous avalanche conditions⚠️
Stick to low-angle terrain and be mindful of overhead hazard. Human-triggered and remote-triggered avalanches remain a serious concern.
A weak layer of faceted grains above a crust is 100 to 200 cm deep and is a recipe for large, high-consequence avalanches. This snowpack setup will take some time to strengthen.
Large storm slabs have formed over the past week and will take some time to strengthen. There is also concern that storm slabs could trigger larger persistent slab avalanches.
Large slab avalanches have been reported continuously over the past week in both the BC and Alberta Rockies (many size 2 and some size 3). They are being triggered naturally, as well as by humans and explosives. They are failing in both storm snow layers and on a persistent weak layer of crust and facets (100 to 200 cm deep).
Human-triggering remains a serious concern in alpine and treeline terrain.
The upper snowpack has 30 to 50 cm of low density snow, with a potential sun crust forming on steep sun-exposed slopes. A widespread crust is buried 100 to 200 cm deep, and weak facets above this crust have been producing large avalanches throughout the Rockies. The snow below the crust is mostly strong and bonded.
