Wind slabs are most likely to be reactive where they have formed on old, faceted surfaces (loose, sugary snow).

Lo esencial
Watch for wind slabs in lee areas. Start with small features before moving into bigger terrain. Observations are limited, verify conditions in your area.

Avalanche Summary
No avalanches have been reported in January.
Observations are limited. Consider posting a conditions report on the Mountain Information Network.

Snowpack Summary
Extreme northwest to southwest wind will likely have stripped all loose snow from exposed areas and deposited it far down slope.
The snowpack in this region is expected to be shallow with the middle and base made up of weak, sugary facet crystals. There is likely a crust at the base of the snowpack as well.
For an idea of old conditions in this area, see this report from our field team.

Terrain and Travel Advice
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
- Wind slabs are most reactive during their formation.
- Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.
