Avalanche Forecast

Fair - Timing of incoming weather is uncertain on Friday

Wednesday: Cloudy with a few snowflakes. Cold (around -20C). Moderate to strong westerly winds. Freezing level valley floor.Thursday: Light snow possible at times. Remaining cold. Friday: The next frontal system is due to hit the region late in the day, bringing moderate-heavy snow, rising temperatures and gusty winds. Freezing level climbing near 1500m by the evening.

Recent reports include a few reluctant slope cut size 1 soft slabs on steep, convex, unsupported features. They had limited propagation and did not run far. Low density storm snow is sluffing readily in steep terrain. In some cases they're entraining considerable mass and reaching up to size 2.

5-10cm additional snow brings storm totals to about 40-50cm. This sits over a variety of surfaces (facets, surface hoar in sheltered areas, soft slabs, hard slabs, wind crust, and a melt-freeze crust below treeline). So far the storm snow has remained relatively cohesionless and has only been reacting as a very soft slab in a few areas. However, I'd expect wind slabs to be developing now in open areas.A surface hoar layer buried in mid-December is gaining strength, but professionals are still treating it with caution, as the consequences of an avalanche on this layer would be high. It's now down about 130cm in the snowpack.
