Riders may be able to trigger slabs at higher elevations. Assess for slabs prior to committing to high-consequence terrain.
Recent snow may have formed slabs that could linger this weekend. Expect the deepest and touchiest slabs at high elevations where the snow surface is smooth.
A widespread avalanche cycle occurred over the past few days with many large avalanches observed. Storm slabs released at higher elevations, which transitioned to primarily loose wet activity on Thursday.
Looking towards the weekend, storm slabs within Thursday and Friday's snow are the most likely avalanche problem. Assess for the bond of all the new snow to the underlying snowpack prior to committing yourself in steep terrain.
Around 30 to 50 cm of snow sits on a hard melt-freeze crust formed from extensive rain earlier this week. Reports suggest the snow is bonding to the snowpack. Periods of elevated wind could redistribute this snow into lee terrain features.
The rain likely moistened the entire snowpack to ground, which is slowly freezing into a crust.
Snowpack depths are approximately 60 to 120 cm at treeline, which rapidly decreases as you lower in elevation.
Friday Night
Clear skies with no precipitation, southwest alpine wind 10 to 20 km/h, treeline temperature -10 °C.
Saturday
Mix of sun and cloud with no precipitation, southwest alpine wind 20 to 30 km/h, treeline temperature -10 °C.
Sunday
Mostly cloudy with 2 to 5 cm of snow, 20 to 40 km/h southwest wind, treeline temperature -6 °C.
Monday
Cloudy with 2 to 5 cm of snow then clearing, 10 to 20 km/h northeast wind, treeline temperature -6 °C.
