    New snow and strong wind have likely formed new wind slabs in lee terrain features at higher elevations. The new snow may not bond well to previous surfaces formed during last week's cold spell.

Confidence

Moderate

Avalanche Summary

No avalanches were reported on Thursday. Looking forward, riders could trigger wind slabs in steep terrain features in wind-exposed terrain.

Please consider submitting a MIN report if you head into the backcountry.

Snowpack Summary

Around 10 to 20 cm of new snow and southwest wind are likely forming wind slabs in lee terrain features at higher elevations. Soft snow prevails in sheltered terrain, which may not bond well to previous surfaces of sugary faceted grains and small surface hoar crystals.

The majority of the snowpack is faceted, with roughly 100 cm found at treeline.

Terrain and Travel Advice

  • 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 old surface.
