Low avalanche hazard means it may be possible to attempt bigger or more extreme lines. Check for pockets of wind slab before committing to high-consequence slopes.

Avalanche Summary
On Friday, a small ( size 1) skier-triggered size wind slab avalanche was reported in the Hudson Bay Mountain area. This avalanche failed on a facet layer that exists above a crust, about 20 cm deep.
Check out this excellent MIN post for full details.
Snowpack Summary
A variety of conditions can be found in exposed terrain at treeline and above, including crusty and wind affected surfaces. In isolated areas in the alpine, hard wind slabs overlie weak sugary facets above a hard crust and may be susceptible to human triggering. In sheltered terrain, there is up to 5 cm of snow on top of a breakable crust and new surface hoar development. The remainder of the snowpack is generally not concerning.

Terrain and Travel Advice
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Problems
Wind Slabs
Rider triggerable wind slabs may exist in isolated areas, mostly in extreme terrain in the alpine. These slabs will be more reactive where they overlie facets on a crust.
