Continually assess the extend of wind effect as you gain elevation. Rider triggerable wind slab could be found on exposed terrain features.

Avalanche Summary
No recent avalanches have been reported in the region.
If you do go into the backcountry, consider submitting a Mountain Information Network report.
Snowpack Summary
Ongoing snowfall accompanied by southerly winds could add to the wind slab problem.
A crusts can be found down around 50 cm on terrain below 1200 m, except on wind scoured slopes where it could be on the surface.
The snowpack is now above threshold for avalanches on smooth slopes at treeline. The snowpack in general is shallower than usual for this time of year and early season hazards are still a concern.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs are most reactive during their formation.
- Use ridges or ribs to avoid areas of wind loaded snow.
Problems
