Points saillants

The new snow and strong west winds have likely formed wind slabs reactive to skier traffic in the upper parts of slopes and below convexities. Travel cautiously and avoid areas where snow has accumulated due to wind.

    With the new snow and strong west winds, new reactive wind slabs have formed on northeast to southeast aspects. They have been deposited over older, more stubborn slabs. The new slabs range from 10 to 40 cm in thickness.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

No new avalanches have been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

We have received between 5 and 10 cm since Tuesday evening.

In the alpine and at treeline, conditions are highly variable, with wind-hardened snow, pockets of powder, wind slabs of varying densities, and areas scoured down to bare ground, particularly on west- and south-facing slopes.

Below treeline, 20 to 40 cm of light snow overlies a progressively denser snowpack, down to basal weak layers of faceted grains and depth hoar.

On solar aspects, a sun crust is present 5 to 30 cm below the surface.

At mid-elevation, the average snowpack depth is around 130 cm.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
