Minimize your exposure to large open slopes capable of producing large avalanches.
Uncertainty exists over the reactivity of buried weak layers.
A layer of facets on a crust is producing large and destructive avalanches across the province. In this region, it is buried 40-90 cm deep and potentially triggerable on steep slopes at treeline and above.
Reports from this region have been limited, with a few small slab avalanches over the past week (size 1 to 1.5). However, neighboring regions have reported numerous large to very large natural and human-triggered persistent slab avalanches. Although not as large or likely in this region, triggering persistent slabs is still a concern.
Surface conditions currently include sun crusts, wind-affected snow, and small amounts of settling snow
A widespread crust that formed in early February is buried roughly 40 to 90 cm deep, possibly with a weak layer of facets above it. In neighbouring regions, this layer has produced many large avalanches over the past week.
The snowpack below this crust is strong and well bonded.
