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.

    Up to 60 cm of recent snow (deeper in wind-loaded terrain) now 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 Thursday, several rider-triggered storm and wind slabs were reported on north to east aspects at treeline throughout the region. Evidence of natural wind slabs up to size 2 were observed in the alpine in the Duffy area in this MIN report.

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

Snowpack Summary

Approximately 30 to 60 cm of recent storm snow has been redistributed by strong to extreme winds in exposed terrain at higher elevations.

The recent snow sits over a widespread crust below 2300 m, formed during last weekend’s rain event.

Another crust is buried roughly 60 to 100 cm deep, surrounded by facets. Although this layer has not produced recent avalanche activity, it continues to be monitored as additional snow accumulates above it.

The remainder of the snowpack is generally strong and well-bonded.

Weather Summary

Friday Night
Mostly clear skies. 1 to 2 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -11 °C.

Saturday
Sunny. 20 km/h northwest ridgetop wind. Treeline temperature -12 °C.

Sunday
Mix of sun and clouds. 2 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -11 °C.

Monday
Mostly cloudy. 1 to 4 cm of snow. 100 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.
