Points saillants

Recent snow may remain reactive due to an underlying crust. Be mindful that sunshine can have a powerful effect on stability - and your desire to push into aggressive terrain.

    Strong solar radiation may weaken large, looming cornices. Carefully manage your exposure to slopes with overhead cornice hazard.

    20 to 60 cm of recent snow overlies a widespread crust. Recent southwest winds have created highly variable snow distribution, with the most reactive and largest slabs expected in wind-loaded areas.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.
  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

On Wednesday and Thursday, explosives and ski cuts produced numerous cornices and storm slab avalanches size 1-2. Observations of natural activity have been limited by visibility.

If you head out, please consider posting your observations to the Mountain Information Network.

Snowpack Summary

20 to 60 cm of recent snow has been redistributed by previous strong to extreme southwesterly winds at upper elevations.

The recent snow sits over a widespread crust below 2100 m. The snowpack below the crust is generally well settled and has no significant layers of concern.

Weather Summary

Friday Night
Partly cloudy. 20 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Saturday
Sunny. 20 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Sunday
Mostly cloudy. 1 to 2 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -8 °C.

Monday
Mostly cloudy. 5 to 30 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Terrain and Travel Advice

  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Be alert to conditions that change with elevation and sun exposure.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
