Monitor surface conditions as you gain elevation and move into wind affected terrain.

Slabs may remain triggerable by riders.

Moderate

Avalanche Summary

No new avalanches have been reported. Reports indicate avalanches up to size 2 occurred during the recent storm.

We expect reactivity to linger in wind affected terrain, while sheltered areas will likely produce loose dry sluffing to rider traffic.

Snowpack Summary

Light snowfall continues to build over around 30 cm of wind affected storm snow above a rain crust. The mid and lower snowpack is well consolidated. Snow depth is between 125 cm and 250 cm at treeline.

Low elevations hold many early season hazards still - rocks, stumps and open creeks lurk at or just below the snow surface. A crust likely exists at the surface, making for challenging travel conditions.

Weather Summary

Monday NightCloudy with 5 to 10 cm of new snow. 20 km/h southerly ridgetop wind. Treeline temperature -3 °C. Freezing level 700 m.

TuesdayCloudy with flurries. 20 km/h southeast ridgetop wind. Treeline temperature -3 °C.

WednesdayA mix of sun and cloud. 10 km/h southeast ridgetop wind. Treeline temperature -4 °C.

ThursdayCloudy with 20 to 30 km/h southeast ridgetop wind. Freezing levels rise to 1500 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Avalanche Problems

Wind Slabs

Reactivity is expected to continue on convex rolls, near ridgelines and on cross loaded slopes.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely
