In sintesi

Consider the terrain below you. Could you avoid being above a terrain trap by riding in a slightly different spot?

As the wind shifts direction on Monday, new wind slabs may form.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2

    Leeward areas with hard snow are where you're most likely to find a wind slab avalanche.

    • Sun: West and southwest aspects aren't likely to have wind slabs.

    • Mon: As the wind shifts to the northeast, wind slabs may build on westerly aspects.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–1.5

    Cornices have been triggered by riders recently. Avoid travelling near or underneath them.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain due to the track and intensity of the incoming weather system.

Avalanche Summary

There have been several natural and rider-triggered wind slab avalanches and cornices on Thursday and Friday. They have been small (size 1) and have occurred in steep wind-loaded features.

Snowpack Summary

There is around 20 to 40 cm of soft snow. In exposed areas, it has been redistributed into lee features by westerly winds.

The midpack is well settled and has no weak layers.

There is a thick, hard crust that makes up the bottom half of the snowpack. The snow above seems to be bonding well to this layer.

Creeks remain open and are a hazard at lower elevations if you're moving fast.

Total snowpack depth is around 100 to 250 cm. Although it is highly dependent on where the wind has blown the snow.

Weather Summary

Saturday Night
Cloudy. 1 cm of snow. 30 to 50 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Monday
Mostly cloudy. 5 to 10 cm of snow. 90 km/h northeast ridgetop wind. Treeline temperature -6 °C.

Tuesday
Mostly cloudy. 1 cm of snow. 35 to 70 km/h northeast ridgetop wind, easing through the day. Treeline temperature -8 °C.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Approach lee and cross-loaded slopes with caution.
  • Watch for areas of hard wind slab on alpine features.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
