Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.




Avalanche Summary

On Sunday, a few small (size 1) natural and skier-triggered wind slab and dry loose avalanches were reported from alpine terrain.

Looking forward to Tuesday, the avalanche problem will likely be confined to newly formed wind slabs in lee terrain features in the alpine and treeline.

Snowpack Summary

New snow accumulates on up to 20 cm of dry, settling snow. Below this, a robust crust or moist snow exists at all elevations except high north-facing.

A second crust formed in late March can also be found in the upper snowpack at variable depths depending on aspect and elevation.

Weak faceted grains sitting on a crust formed in early February are now buried 100 to 180 cm. This layer has generally been gaining strength and is unlikely to be human-triggered in areas where a supportive crust is present above it.

Terrain and Travel Advice

  • Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
  • Wind slabs may be poorly bonded to the underlying crust.
