In sintesi

Continuously assess conditions and look for signs of instability as you move through terrain.

Wind slabs are most reactive during their formation.

    A crust from early February has produced avalanches in the region. This layer is problematic where facets overlie it.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in the past couple of days.

Snowpack Summary

Around 20 cm of new snow has buried a variety of layers including surface hoar in sheltered terrain, a crust on south and west facing slopes as well as old wind slab on exposed terrain. A new crust may be found on sun exposed terrain and all aspects below treeline.

Another layer of surface hoar is down around 30 cm in sheltered areas.

The widespread crust buried in early February is down 40 to 60 cm and has sugary facets on top.
