Regions

Glacier.

Challenging ski conditions exist at lower elevations with thin coverage and a crust of variable thickness.

Watch out for early season hazards.

Confidence

Moderate

Avalanche Summary

No new avalanches observed over the last few days.

Late last week, several avalanches up to size 3.0 were observed in the highway corridor and in the Connaught area. Some of these avalanches ran to ground in lower elevation runout zones.

Snowpack Summary

A crust of varying thickness and strength exists up to 2200m. Above this elevation, dry snow can still be found but isolated pockets of windslab may still be lingering near ridgetop in the Alpine.

Weather Summary

A storm is on track to reach us Saturday night bringing much awaited precipitation.

Tonight: Mainly cloudy with isolated flurries. Alpine low -5°C. Wind SW 25km/h. Freezing Level (FZL) 1300m

Fri: Cloudy with isolated flurries. Alpine high -4°C. FZL 1400m. Wind SW 30km/h

Sat: Snow. 19cm. Alpine high -4°C. FZL 1500m. Wind SW 40 km/h

Sun: Snow. 15cm. Alpine high -3°C. Wind SW 40. FZL 1600m

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
