Avalanche Summary

No new avalanches were reported in this region on Friday. However, it is likely that numerous natural loose wet avalanches occurred during the storm on Friday at treeline and above.

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.

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.

Confidence

Moderate - Due to the number of field observations
