The Likelihood of triggering a persistent slab is uncertain
Recent new snow has been redistributed by wind blowing from a variety of directions.
A weak layer of facets and/or surface hoar may rest above a hard-melt freeze crust that formed early February. This layer remains in the depth for human triggering .
Only a few natural size 1.5 wind slab avalanches have been reported over the past few days.
Over the past week in the neighbouring region, many natural and skier triggered persistent slab avalanches occurred on the facets above the early-February melt-freeze crust described in the Snowpack Summary.
Winds have come from a variety of directions over the past couple days. Wind effect could be found on all aspects.
30 to 50 cm overlies a layer of surface hoar in wind-sheltered terrain, weak facets, or a hard melt-freeze crust on south and west-facing slopes.
A thick and hard widespread crust that formed in early February is buried about 60 to 80 cm deep. This crust may have a layer of facets above it.
The eastern portion of this region is much shallower with a highly variable and wind effected snowpack.
