Kernpunkte

This last storm has dropped 15cm in our East region and around 5cm on the Spray road.  The recent wind slabs are now buried so use caution when approaching slopes.

    New snow is now covering the recent wind slabs in the Alpine and open areas at Treeline and below.

    A weak layer down 35 to 40cm in the snowpack seems prime for human triggering in steep and unsupported terrain.

  • Deep Persistent Slabs

    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit

    The November crust buried 50 to 90cm in the snowpack has become reactive to snowpack stability tests. Triggering is more likely in shallow snowpack areas and rocky features.

Weather Forecast

Monday is forecast for isolated flurries and cold temperatures. Winds are expected to be light from the East. Monday and Tuesday are expected to be sunnier yet remain on the cool side.

Avalanche Summary

No new avalanches have been observed in the last 24 hrs.

Snowpack Summary

10-20cm snow has fallen in the eastern region from an upslope storm but only 3-5cm along the divide area. Our first main concern continues to be failures on the November crust down 40-60cm in open wind affected areas. This November crust seems to be more reactive in snowpack tests over the past few days. Our second concern is the persistent slab that is now buried under this new snow reacting to the faceted layer down about 35-50cm.
