These will be concentrated to immediate lee areas for now. As winds increase, expect them to move lower and become larger

Watch tomorrow's freezing levels. It wouldn 't take much change in temperature or precipitation input to push the treeline hazard to considerable.

We are still suspect of this layer. Expect it to be intact and reactive at upper elevations.

Moderate - Timing, track, or intensity of incoming weather system is uncertain
Weather Forecast
Flurries overnight with more significant snow starting around noon tomorrow. We are expecting 20cm by Sunday night. As any experienced local would guess, the accompanying SW winds will be strong (55-70km/hr) as the storm plays through. Freezing levels will climb up to 2200m tomorrow. Temperatures will fall as the storm passes.
Avalanche Summary
A few recent avalanches were noted on various aspects. They were up to sz2.5, and in confined areas/gullies they ran quite far. All of them originated from steep cliff terrain and pulled out slabs below.
Snowpack Summary
There were a few scattered flurries today, but no significant accumulation. The 10-15 cm from yesterday has helped to cover the crust and at upper elevations has likely improved the ski quality, however that can't be confirmed first hand. The latest crust is thought to be as high as 2500m on all aspects, and quite thick given the extended length of the warm spell/rain. Given the new snow and recent SW winds, fresh wind slabs are expected in immediate lee areas in the alpine.
