Points saillants

Recent snow has significantly increased and altered the snowpack at higher elevations. Make conservative terrain choices while the new snow settles and bonds.

    As storm snow continues to accumulate, reactive slabs could exist at all elevations. Deeper and more reactive slabs are likely in wind-loaded, northerly terrain at higher elevations.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.
  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary

No recent avalanche activity has been directly observed in the past several days. However, a widespread avalanche cycle in neighbouring regions suggests that significant natural avalanche activity has likely occurred since Tuesday.

Natural avalanche activity remains possible with continued storm snow accumulation.

Snowpack Summary

Stormy conditions continue to significantly build the previously thin snowpack. Beneath the recent snowfall, the snowpack is generally well-settled, consisting of moist, dense snow.

Snow depths at the treeline are estimated to range from 50 to 100 cm.

Weather Summary

Friday night
Cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Saturday
Cloudy. 20 to 25 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Sunday
Cloudy. 20 to 40 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -4 °C.

Monday
Mostly cloudy. 30 to 50 cm of snow. 50 km/h south ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Don't let storm day fever lure you into consequential terrain.
