Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Summary
No new avalanches were reported in this region on Thursday.
If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.
Snowpack Summary
5-15 cm of new snow and light to moderate southwest wind have formed small wind slabs on lee features in the alpine.
Below the recent snow is a melt-freeze crust, existing on all aspects at treeline and below. The crust extends to mountain tops on sunny aspects. In north facing high alpine terrain the surface snow may have remained cold and dry.
The mid and lower snowpack consists of a number of old crusts and facetted snow that continue to be monitored, particularly in shallow snowpack areas.

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.
- Avoid exposure to slopes that have cornices overhead.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Problems
Wind Slabs
Small wind slabs may build with light snowfall and southwest winds. Watch for reactive wind slabs in isolated locations in the alpine.
