New wind slabs could form with moderate north winds in the forecast. Expect this problem to be more reactive on south through southeast aspects.

While travelling in avalanche terrain, be especially cautious of cohesive slabs overlying a sugary, weak lower snowpack.

Plenty of early season hazards, such as buried rocks and tree stumps still exist.

High

Avalanche Summary

No new avalanches have been reported in the past few days in the region.

Snowpack Summary

40 - 80 cm of snow continues to bond and settle over a generally weak sugary, facetted mid and lower snowpack. Isolated pockets of wind slab persist in wind exposed terrain at higher elevations.

Snowpack depths are highly variable, ranging from 80-180 cm in the alpine. Below treeline the snowpack is thin and sugary making it a challenge to access terrain in many areas without damaging your sled or skis.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Problems

Wind Slabs

An icon showing Wind Slabs

Isolated pockets of cohesive, wind slabs remain an issue in upper elevations on exposed terrain features, near ridges and highpoints. Be aware that new winds slabs have the potential to form on south and southeasterly aspects with the incoming north flow.

Aspects: All aspects.

Elevations: Alpine, Treeline.
