An increasing wind slab problem will build as flurries accumulate. If you find pockets deeper than 15 cm, investigate the bond between new snow and old surfaces.
On Thursday, a skier triggered a small, thin wind slab at an entrance to a northwest-facing slope.
On Friday afternoon, loose, dry avalanches and pinwheeling were observed in steep rocky terrain in the sun. As the sun pokes out and temperatures warm, loose wet avalanches may become possible.
Expect to find wind-pressed surfaces, with deeper and more reactive pockets around ridgelines at upper elevations; and a widespread crust in wind-scoured areas and lower elevations. On steep sunny slopes and lower elevations, the surface crust may soften with warming during the day, or the snowpack may become isothermal.
A layer of weak, faceted crystals overlying a crust is buried 30-60 cm in the east of the region and 50-100 cm in the west. Triggering this layer has become unlikely, except in the case of shallow snowpack spots or very large loads like cornice falls.
