Be vigilant with the approaching weather and the potential for newly forming wind slabs to become reactive.

Moderate

Avalanche Summary

No significant avalanches were reported.

Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network.

Snowpack Summary

The snow surface varies from a sun crust on solar aspects to Surface hoar on northerly aspects. The new snow forecasted will recover these surfaces.

The mid snowpack is generally well settled, with an early November crust buried 50 to 100 cm deep.

Snow depths at treeline range from 100 to 170 cm and decrease quickly at lower elevations.

Weather Summary

Thursday Night

Mainly cloudy. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing levels 700 m.

Friday

Flurries. New snow 5 to 15 cm. 15 to 30 km/h southerly ridgetop wind. Treeline temperature -2 °C. Freezing levels 1000 m.

Saturday

Snow, heavy at times. New snow 15 to 30 cm. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing levels 1300 m.

Sunday

Mostly cloudy with isolated flurries. 20 to 30 km/h northwest ridgetop wind. Treeline temperature -6 °C. Freezing levels 1000 m.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.

Avalanche Problems

Wind Slabs

The severity of the wind slab problem will primarily depend on the amount of new snow and the strength of the wind. It is very likely that the wind slabs will have poor bonding to the old snow surface.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
