In sintesi

7 AM Update: Reactive storm slabs have built overnight. Choose conservative terrain and give the new snow time to bond.

Problemi valanghivi

  • Cornices

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

    Cornices remain a concern. Avoid travelling on or under large cornices, especially if you see blowing snow.

  • Loose Wet

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

    Wet avalanches are possible where recent precipitation fell as rain. Avoid travelling above or in terrain traps.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely - Very Likely
    Dimensione
    1–2

    Recent snow and southwesterly winds have built new slabs. Slabs may be more reactive where a buried surface hoar layer is present.

Confidence

Moderate

  • Uncertainty is due to limitations in the field data.

Avalanche Summary

Sunday

  • A natural size 1.5 storm slab occurred

  • Skiers intentionally cut small size 1 slabs and cornices in the Lizard Range.

Saturday

  • Several size 1 to 1.5 slabs were reported in alpine and treeline terrain across the region.

  • Skiers accidentally triggered wind slabs on Mt.Fernie (MIN post here) and in Cabin Bowl.

  • A natural cornice-triggered avalanche was also reported - see photos.

Looking forward

  • We expect wind slabs & cornices to remain triggerable on Tuesday.

Snowpack Summary

Recent snow, combined with strong southwesterly winds and relatively warm temperatures, has built large cornices and new slabs, particularly near ridgetops. The snow surface is wet at lower elevations from rain and warm air.

A weak layer of surface hoar can be found in some sheltered terrain features buried 40 to 60 cm. In other areas, a melt-freeze crust can be found at similar burial depths, up to around 2000 m.

The remaining snowpack currently has no layers of concern.

Weather Summary

Monday Night
Cloudy. 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Tuesday
Cloudy. 0 to 2 mm of precipitation as snow or rain at treeline. 40 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 2100 m.

Wednesday
Mostly sunny. 50 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level rising to 3700 m.

Thursday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level around 1400 m.

Terrain and Travel Advice

  • Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Keep in mind that the high density of wet avalanches can make them destructive.
