Wind slabs are expected to remain reactive. Use caution around ridgelines, and watch for signs of instability

Moderate
Avalanche Summary
Size 2 natural avalanches were observed on Monday on west facing slopes, and cross loaded features in the alpine. Check out this MIN report for more details.
We expect natural activity to have tapered off, but human triggering still remains possible.
Snowpack Summary
15-40 cm of recent snow sits over weak, faceted surfaces and may be slow to bond. At upper elevations, it has been redistributed by shifting winds. Check out this MIN report from the weekend, describing snowy conditions in high terrain.
Another layer of weak, faceted crystals and a crust are buried 20-50 cm deep. The mid and lower snowpack is generally well-bonded and strong.
Weather Summary
Tuesday Night
Mostly cloudy with flurries bringing up to 5 cm. 40-70 km/h south ridgetop wind. Treeline temperature -15 °C.
Wednesday
A mix of sun and cloud. 20-30 km/h southwest ridgetop wind. Treeline temperature -10 °C.
Thursday

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
Problems
Wind Slabs
The freshest and most reactive wind slabs will likely be forming on north and east facing slopes as winds shift to southwest.
On other aspects, older wind slabs are likely to remain reactive as they sit over weak surfaces.
Aspects: All aspects.
Elevations: Alpine, Treeline.
