Watch for small wind slabs and sluffs in steep terrain, and as always, practice good travel habits to reduce your risk.

One small slab avalanche (size 1) was triggered remotely by a group of skiers on Sunday. It was 40 cm thick and occurred on an east aspect at 1400 m.On Wednesday, there were several size 1-2 human triggered slab avalanches near Terrace. A few of these were triggered remotely (from a distance). These were on north and west aspects around 1400 m. Similar activity had been reported in this area over the previous week, but has quieted down recently.

The region has seen strong wind from various directions, leaving hard wind slabs on most aspects in exposed terrain. South facing slopes likely have crusts on the surface. Roughly 30-50 cm of snow sits above a layer of cold, soft faceted snow and surface hoar. This layer has been reactive in some snowpack tests and could enhance the propagation of wind slabs, especially on north and west alpine features. The lower snowpack is generally considered strong.
