Lo esencial

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.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    No change of any consequence...hard slabs in open areas at and above treeline.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    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!

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.

Avalanche Summary

Only a few loose dry sluffs from steep rocky terrain observed during a day long snow survey flight over most of Kananaskis Country.

Snowpack Summary

Some surface hoar in sheltered locations at and below treeline was observed on Tuesday.  WIndward slopes have been stripped bare by winds over the past several days
