In sintesi

The weak basal facet layer could re-awaken with any significant loading.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2
    New snow with variable wind directions and speeds have translated to wind loaded pockets of storm slab potentially overlying weak surface facets. Loose avalanches are also possible.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    Bridging above this layer makes it stubborn to initiate; however, it will be big when it goes. A sudden warming, large additional snowload, large triggers, or surface avalanches may tip the scale. Be aware of thin locations as likely trigger spots.

Weather Forecast

Forecast of a few flurries and moderate to strong SW winds should maintain the current avalanche conditions.

Snowpack Summary

In the Icefields, winds are whipping up what little snow is available. Recent snowfall overlies a layer of small surface hoar and surface facets. A relatively hard mid-pack is providing bridging strength over weak basal facets at tree line and above. Below treeline it is supportive mid-pack where 70cm HS.

Avalanche Summary

Some loose snow slides observed out of steep terrain in the alpine (size 1.5).

Confidence

Due to the number of field observations on Thursday
