Highlights

Wind slabs remain the primary concern, approach ridgelines with caution.

    Reactivity is expected to continue on convex rolls, near ridgelines and on cross loaded slopes.

    Wind slabs could step down to buried crusts, most likely to be triggered by large loads at or above 1900 m.

Moderate

Avalanche Summary

Observations have been limited in this region. We expect wind slabs will continue to be reactive to rider triggering.

Please share any observations or photos to the Mountain Information Network (MIN).

Snowpack Summary

Up to 30 cm of wind affected snow sits above a crust, which exists up to 1900 m.

Another crust is buried 60 to 100 cm deep, and in sheltered terrain a layer of surface hoar may exist just above it. There is uncertainty over its reactivity. It is more likely to be a concern in wind affected, thin and rocky start zones at higher elevations.

Snow depths at treeline vary between 90 to 160 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
  • Be aware of the potential for large avalanches due to buried weak layers.
