Warm temperatures up high may increase the likelihood of triggering an avalanche.

Confidence

Low

Avalanche Summary

On Thursday, two large (size 2) wind slabs failed naturally on steep northeast aspects in the alpine.

Several natural and rider-triggered avalanches, up to size 2.5, were reported on the 18th and 19th of January. A number of these reports occurred on the weak layer from early December.

Snowpack Summary

Recent snow has been heavily wind-affected in exposed areas. A crust exists below 1250 m, making for challenging travel conditions.

A weak layer of facets and a crust from early December is buried roughly 50 to 100 cm deep.

Weather Summary

Saturday Night

Clear. 20 to 30 km/h northwest ridgetop wind. Treeline temperature -7 °C with a temperature inversion.

Sunday

A mix of sun and clouds. 20 to 30 km/h northwest ridgetop wind. Treeline temperature -4 °C with a temperature inversion.

Monday

Sunny. 20 to 50 km/h west ridgetop wind. Treeline temperature 0 °C, inversion breaking down.

Tuesday

Mostly cloudy. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Avalanche Problems

Persistent Slabs

A widespread crust with facets is buried 50 to 100 cm deep. Wind slabs may step down to this layer, producing large avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3

Wind Slabs

Watch for steep convex rollovers, ridgetop entrances, and cross-loaded features.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5

Loose Wet

Warm temperatures up high may cause the surface to become wet.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5
