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

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.
  • We are confident the likelihood of avalanche will increase with the arrival of the forecast weather.

Avalanche Summary

No recent avalanche activity has been reported in the past several days. However, storm slabs have been reactive to riders and avalanche control in the neighbouring Sea to Sky region, and both regions have experienced similar stormy weather.

Natural avalanche activity remains possible with continued storm snow accumulation.

Snowpack Summary

Stormy conditions continue to significantly build the previously thin snowpack. A thin melt freeze crust caps most surfaces or is just under the most recent flurries. This covers up to 30 cm of snow which accumulated through the week.

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

Saturday night
Cloudy. 10 to 15 cm of snow. 30 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 -3 °C.

Monday
Mostly cloudy. 25 to 60 cm of snow. 50 km/h south ridgetop wind. Treeline temperature -4 °C.

Tuesday
Mostly cloudy. 20 to 40 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -5 °C.
