If the new snowfall surpasses 30 cm, the danger level in the alpine and at treeline is deemed considerable.
Travel carefully at lower elevation due to low snowpack conditions.

Avalanche Summary
No new avalanches were reported before 4pm on Monday.
If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.
Snowpack Summary
New snowfall and strong south winds are expected to build new wind slab. Past storm snow depths from 10 to 20 cm has bonded well to old surfaces Below the treeline, expect to encounter dirt or shallow, dense, moist, or wet snow.
The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.
Overall, the snow depth remains shallow, especially on south facing slopes. Early season hazards are just below the surface.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
- Travelling on skis is hazardous due to a very shallow mountain snowpack.
Problems
Wind Slabs
Past snow available for wind transport and new snow fall will continue to develop wind slabs on lee aspect terrain. During periods of very strong wind, expect wind slabs to be located lower on lee slopes.
Aspects: North, North East, East, South East, North West.
