Points saillants

Choose low consequence terrain.

The combination of 40 cm of storm snow, strong wind, and a persistent weak layer means rider triggered avalanches are likely.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Likely
    Taille
    1–2.5

    Expect to find new, reactive slabs on north and east facing slopes. Wind slabs will be largest and most reactive around White Pass.

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1.5–3

    A widespread layer of facets sits 70-100 cm deep, formed during prolonged cold. It is most likely to be triggered where the snowpack thins rapidly.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.
  • Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.

Avalanche Summary

A natural avalanche cycle occurred Tuesday night. Early reports are of natural avalanches up to size 2.

Snowpack Summary

Up to 40 cm of recent storm snow overlies a variety of surfaces including facets, surface hoar, and wind pressed snow. Deeper deposits will be found on north facing slopes due to strong southerly wind.

The lower snowpack is made up of 60 to 100 cm of weak facets

Snowpack depths vary widely due to wind, but average around 160 to 220 cm in the alpine across the region.

Weather Summary

Wednesday Night

Partly cloudy. 1 cm of snow. 15 km/h southwest ridgetop wind. Treeline temperature -16 °C.

Thursday

Mix of sun and clouds. 2 to 5 cm of snow. 20 km/h southwest ridgetop wind in the morning , increasing to 40 km/h in the late afternoon. Treeline temperature -18 °C.

Friday

Mostly cloudy. 2 to 5 cm of snow. 25 to 40 km/h south ridgetop wind. Treeline temperature -16 °C.

Saturday

Mostly cloudy. 5 to 10 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Keep in mind that human triggering may persist as natural avalanches taper off.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
