Large human triggered avalanches are possible.
Evidence of a persistent weak layer may be hard to find. Conservative terrain choice is the best way to avoid this avalanche problem.

Moderate
Avalanche Summary
On Monday, avalanche reports were limited to small, loose dry avalanches on slopes in the sun.
The persistent avalanche problem is slowly improving but deserves patience and continued vigilance in conservative terrain choices. The most recent avalanches on this layer occurred on January 2 and 3 with large triggers.
Snowpack Summary
A thin crust overlies 20 to 30 cm of soft snow in most areas. This sits on a layer of surface hoar in isolated locations and a crust on sun-affected slopes.
A persistent weak layer that consists of a crust with overlying facets and/or surface hoar is buried 90 to 120 cm. This layer is widespread but trending to unreactive. It is most likely to be problematic on north through east-facing slopes between 1700 and 2300 m.
At treeline, snow depths range from 100 to 180 cm.

Terrain and Travel Advice
- Carefully evaluate big and steep terrain features before committing to them.
- Carefully evaluate steep lines for wind slabs.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
Problems
Persistent Slabs
Sporadic persistent slab avalanches continue to occur. While this avalanche problem is becoming more difficult to trigger, it comes with serious consequences.
