{"blocks":[{"key":"2svin","text":"On Wednesday, natural storm slabs up to size 2.5 typically releasing down 20-40 cm, some of which were failing on a layer of surface hoar. Natural loose dry avalanches were being reported in extreme terrain at higher elevations and one loose wet avalanche was triggered at lower elevation. Humans and explosives were also triggering a variety of avalanches in the storm snow. On Tuesday, a variety of natural and human triggered avalanches up to size 2.5 were observed.

Concern for persistent slab activity like this is being sustained by new snow, wind, and warming. On Monday, a few very large simultaneous remote triggered persistent slab avalanches were reported in this Mountain Information Network (MIN) report south of Kaslo. It reported as a near miss, triggered from 150 m away on northeast through southeast features around treeline. The crown was one meter deep and propagated 500 m wide. On Friday, three naturally triggered size 2-3 avalanches on this layer were reported in mountain ranges just west of the Columbia river. They were reported at treeline and above on south and east aspects. Some were known to be wind slab avalanches that stepped down to this deeper, persistent layer in a thin, rocky area.
