Moderate

Avalanche Summary

No new avalanches observed.

Snowpack Summary

5–10 cm of new snow rests on wind slabs up to 20 cm deep in open, wind-affected areas and on a crust 5 -30 cm thick everywhere else except for sheltered north-facing slopes. The January drought layer lies 40–100 cm deep, with snow depths at treeline averaging 130–200 cm.

Weather Summary

We expect some snow on Thursday and cooler conditions Friday and Saturday. See the table below for a more detailed forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.

Avalanche Problems

Wind Slabs

Wind slabs will continue to form throughout next three days with new snowfall and southwest winds up to 50 km/hour.

Aspects: North, North East, East, South East, North West.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2

Persistent Slabs

This problem remains a concern on high northerly aspects where the surface crust is thin or non-existent.

Aspects: North, North East, North West.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 1.5 - 3
