Avalanche Summary
The Field Team observed a size 2 wind slab avalanche on an east aspect in the alpine in Powder Valley that probably occurred on Wednesday, from steep, rocky terrain.
We haven't received any other recent reports of avalanches. Looking forward, it remains possible for riders to trigger wind slabs in steep, lee terrain features.
If you head into the backcountry please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
5 to 15 cm of recent snow overlies hard surfaces. This new snow may be redistributed into wind slabs in exposed areas from southwest winds.
The mid and lower snowpack is generally strong. A thick, well-bonded melt-freeze crust is approximately 30 to 50 cm above the ground at elevations below 1200 m.
Snowpack depths range from 80 to 200 cm across the region and vary locally from wind distribution.

- Carefully evaluate big/extreme terrain features before committing to them, it may not be full "go" time yet.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
