Avalanche Summary

Several explosives triggered Deep Persistent Slabs, up to size 2, were reported by the ski hill on Wednesday. A good reminder that this problem is not going away, and triggering full depth avalanches is still a possibility.

Snowpack Summary

Up to 10cm of new snow has fallen with generally very light winds.

The snowpack is mostly made up of facets and ranges in depth from 60 to 120 cm at treeline and above. At the bottom of the snowpack there are multiple early season crusts with facets above and below.

Weather Summary

Friday

Cloudy with sunny periods and isolated flurries.

Precipitation: Trace.

Alpine temperature: High -8 °C.

Light ridge wind.

Saturday

Cloudy with sunny periods.

Precipitation: Nil.

Alpine temperature: Low -12 °C, High -5 °C.

Ridge wind light to 15 km/h.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Be especially cautious as you transition into wind-affected terrain.

Avalanche Problems

Deep Persistent Slabs

A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
