Avalanche Forecast

Moderate

Over the past couple days there have been several reports of natural, skier and cornice triggered wind slab avalanches, the largest of which were size 3.

On Wednesday, skiers triggered a large, size 2 avalanche near Ningunsaw. The Deep Persistent avalanche was triggered on an east aspect near ridgetop in a thin, rocky start zone and failed on basal facets.

Strong to extreme southwest winds have loaded north and east aspects and pressed or scoured others. Up to 80cm of recent storm snow sits on a crust layer from late January.

Check out this MIN for some great recent observations of the snowpack.
