    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Large hanging cornices will weaken with rising temperatures. Use caution traveling below or near them.

  • Loose Wet

    Probabilidad
    Possible
    Tamaño

    Pay attention to daytime warming and stay away from sunny slopes in the afternoon

  • Deep Persistent Slabs

    Rising temperatures will increase the likelihood of triggering this problem. Shallow areas are likely trigger spots.

Weather Forecast

Very light amounts of precip in the overnight forecast (>1mm). Mostly sunny on Thursday with alpine temperatures expected near +1 by the afternoon with light west winds. Freezing levels rising to 3200m on Friday with mostly sunny skies.

Snowpack Summary

Supportive crust (20cm to 3cm) at tree-line and below, making travel easy on skis. Persistent slab, 30 to 70cms thick, reacting to compression tests on facets in the low moderate range. Expect to see this more reactive underfoot as crust breaks down and freezing level rises. Mod - Strong winds pushing small amount of HN into pockets of slab.

Avalanche Summary

Old activity to size 2.5, mostly on solar aspects observed by field teams along the Icefields Parkway. Mix of loose wet and slab avalanches observed.
