Avalanche Summary

We haven't received any reports of recent avalanches. Looking forward, we expect that riders could trigger newly formed wind slabs in wind-loaded alpine terrain.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

The alpine has received upwards of 45 cm of snow over the past few days, with more forecast for Friday. Strong southwest wind is also forecast, which may redistribute the snow to cross-loaded and lee terrain features. Wind-protected areas surfaces remain soft.

Cornices are large and looming at this time of year.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs are most reactive during their formation.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Wind Slabs
