Points saillants

We have had up to 40 cm of new snow in the last 4 days, great ski conditions right now but treat steep slopes with caution as new storm slabs may be human triggerable.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.
