Avalanche Summary

One size 2 natural and a few human-triggered avalanches were reported since Friday.

Observations are limited at this time.

Snowpack Summary

Exposed areas are heavily wind-affected. Up to 50 cm of new snow overlies a surface hoar layer in sheltered areas. In sun-exposed terrain, new snow overlies a crust, while elsewhere it sits atop a mix of old wind-affected surfaces and weak, faceted snow.

A widespread crust with facets and/or surface hoar, buried in mid-January, is approximately 60 to 120 cm below the surface.

The mid and lower snowpack is well-settled.

Weather Summary

Saturday night

Cloudy with 0 to 5 cm of snow. 10 to 20 km/h south ridgetop wind. Treeline temperature -25 °C.

Sunday

Mostly cloudy. 10 to 20 km/h east ridgetop wind. Treeline temperature -25 °C.

Monday

Scattered cloud. 20 to 40 km/h east ridgetop wind. Treeline temperature -25 °C.

Tuesday

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

Avalanche Problems

Storm Slabs

New snow and wind have formed reactive slabs over a weak layer of surface hoar.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1.5 - 2.5
