New snow and wind have built fresh wind slabs at higher elevations. Evaluate wind-affected terrain carefully as human-triggered wind slab avalanches are possible.

Avalanche Summary
There have been no new reports of avalanche activity in the region over the past few days.
If you are getting out in the backcountry, let us know what you are seeing by making a post on the MIN (Mountain Information Network).
Snowpack Summary
5 to 20 cm of storm snow covers the surface at higher elevations. As winds pick up the new snow will be redistributed by primarily southwest wind into lee terrain features at alpine and treeline. The new snow sits atop a hard crust on all aspects to at least 1600 m. Below the crust, the snowpack is generally settled and well-bonded.
Weather Summary
Tuesday Night
Partly cloudy with 1 to 3 cm of snow at upper elevations. Ridgetop wind west 30 to 50 km/h. Treeline temperature -6 °C. Freezing level drops to valley bottom.
Wednesday
Mix of sun and cloud. Ridgetop wind southwest 15 to 30 km/h. Treeline temperature -1 °C. Freezing level 1700 m.
Thursday
Cloudy with 4 to 8 cm of snow at upper elevations. Ridgetop wind southwest 20 to 40 km/h. Treeline temperature 0 °C. Freezing level 1700 m.
Friday
Partly cloudy with 0 to 4 cm of snow at upper elevations. Ridgetop wind southwest 15 to 30 km/h. Treeline temperature 0 °C. Freezing level 1800 m.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs may be poorly bonded to the underlying crust.
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
