Avalanche Summary
No new avalanches were reported in this region on Thursday. However, avalanche activity is expected to increase on Friday with the forecast rain to mountain-tops.
On Tuesday, a party skiing near Kootenay Pass reported "whumphing" on solar aspects near ridgetops and triggered a size 2 storm slab avalanche sitting on a crust on a north aspect at around 2000 m. See the MIN report HERE.
On Sunday, a skier triggered a small size 1 wind slab that then stepped-down and triggered a size 2.5 persistent slab avalanche on a northwest aspect in the alpine. See the MIN report HERE.
Snowpack Summary
Rain to mountain-tops Thursday night has soaked 20-40 cm of recent snow and initiated a loose wet avalanche cycle at treeline and above.
Below treeline, the snow is disappearing rapidly.
