Avalanche Summary

Small wet avalanches were produced yesterday with warm temperatures and snowfall.

Wet avalanches are expected to be unlikely on Friday, however riders may be able to trigger wind slabs at higher elevations - above the freezing line.

Snowpack Summary

Recent snowfall has reached 50 cm in some areas, with reports indicating this new snow is bonding well with the old snow surface. Wind affect may be found on north facing slopes at higher elevations.

The recent snow sits atop a widespread crust layer and a dense and well-bonded snowpack.

Terrain and Travel Advice

  • Investigate the bond of the recent snow before committing to your line.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
