Evaluate terrain carefully. Steep open slopes may have a buried weak layer capable of producing large avalanches.
We are uncertain about this problem. A layer of facets on a crust is producing large scary avalanches across the province. It is 40 to 80 cm deep in this region, 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 settling powder.
A widespread crust that formed in early February is buried roughly 40 to 80 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 bonded.
