Watch for fresh and reactive wind slabs as you move in to wind affected terrain. Head to sheltered terrain for the best chance of good riding conditions.

Avalanche Summary
There have been no reports of recent avalanche activity within the last 3 days.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
New snow falls over wind affected surfaces at higher elevations, and over a crust below 2000 m.
The snowpack below is considered settled. Weaker layers exist but thick crusts exist above, limiting likelihood of triggering these layers for now.
Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m. This is about 60% of an average year.
Weather Summary

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Carefully evaluate steep lines for wind slabs.
- Make observations and assess conditions continually as you travel.
Problems
Wind Slabs
Expect fresh wind slabs to build as fresh snow is redistributed by southwest winds. Take care around ridge crests and wind loaded features. Older wind slabs below the fresh snow may still be reactive to human triggers as well.
