Lo esencial
Wind slab size and reactivity will increase with new snow and wind, burying a slippery crust.

Snowpack Summary
As much as 25 cm of new snow continues to accumulate atop a widespread surface crust. Beneath, the upper snowpack is moist. Where still intact, a crust buried in January may be found 100 to 150 cm deep. Below this, the snowpack is well-bonded and stable. At lower elevations, snow coverage is thin.
Confidence
Moderate
Avalanche Summary
No recent avalanches have been reported. Looking forward, wind slab avalanches become increasingly likely as new snow accumulates.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- Closely monitor how the new snow is bonding to the crust.
