    Small pockets of wind slab may develop on lee terrain features at upper elevations with bits of new snow. Even small avalanches could be particularly dangerous due to obstacles that are exposed or just below the surface.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported. Recent wet snow and rain may have caused wet loose avalanches in steep terrain, but field observations are limited.

If you head into the backcountry by any method of travel, please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

15-25 cm of moist snow or a frozen crust may be found on the surface at uppermost elevations. This recent snow is settling rapidly and bonding well to the warm and moist snow beneath. The snowpack below 1500 m has been soaked with rain or diminishing rapidly. Total snow depths at ski hills and remote stations are 50 to 70 cm, with closer to 100 cm possible at treeline. Many areas are below the threshold depth for avalanches.
