In the Dogtooth Range on Friday, skiers initiated a cornice fall which triggered a size 2.5 slab avalanche on the slope below. In the same area on Saturday a size 2 slab was rider triggered from a ridge crest. A size 2 natural slab avalanche was observed on Saturday further south in the region. The February 10th interface is thought to have been the culprit in all of these events.

Monday: Light to locally moderate snowfall / Moderate to strong southerly winds / Freezing level at 1200mTuesday: Light to locally moderate snowfall / Moderate to strong southwest winds with extreme gusts / Freezing level at 1200mWednesday: Mix of sun and cloud with a possibility of flurries / Light ridgetop winds / Freezing level at 800m

Fair - Forecast snowfall amounts are uncertain on Monday

Light amounts of new snow are expected to overlie weak surface hoar in sheltered areas, a sun crust on solar aspects and thin wind slabs in exposed terrain. These new accumulations are likely to be reactive as a wind slab in pockets of exposed terrain.The big news remains a mix of weak surfaces which were buried on February 10th. This persistent interface lies between 50 and 120cm below the surface, and includes surface hoar, well developed facets and a mix of hard surfaces which remain widespread at all aspects and elevations. Although natural avalanche activity has tapered-off at this interface, destructive avalanches are still a very real concern with ongoing reports of human triggering, whumpfing and sudden/easy snowpack test results. The mid and lower snowpack are generally strong and well consolidated. Weak basal facets exist in many areas, but triggering has now become unlikely.
