Points saillants

Snow cover is highly variable and thin weak spots are abundant.  Natural avalanche activity is minimal but here are opportunities out there for skier triggering in areas with thin snow cover.  Watch for buried hazards in the form of stumps, logs etc.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–3
    No change of any consequence...hard slabs in open areas at and above treeline.

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–4
    Little change here either...the basal facets provide varying support depending upon how thick the snowpack is - the thinner the snow cover, the more the likelihood of skier triggering is!

Confidence

Good

Weather Forecast

Clear skies will dominate over the next couple of days but temps will decline slightly with the freezing level at the surface (@1700m).  Winds will lessen on Wednesday and climb back up to more moderate values for Thursday.  No new precipitation until at least the weekend.
