Avalanche Summary
No recent avalanches have been reported. Looking forward, wind slab avalanches become increasingly likely as new snow arrives.
Snowpack Summary
5 to 15 cm of new snow accumulates over a widespread surface crust. Below, the upper snowpack is wet. 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.

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