Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–3
    Moderate to strong Westerly winds will be forming wind slabs below lee ridgelines on Sunday.

  • Loose Dry

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione

    If the sun peaks out, loose avalanches with significant mass may occur. They are initiating out of steep West or South facing high elevation rocks or gullies.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    The storm slabs remain soft where the wind has not firmed them up. Soft slab conditions also exist on gully sidewalls and some large alpine slopes.

Weather Forecast

Some light flurries (rain showers in valley bottoms) possible on Sunday as a frontal systems moves through.  Westerly winds will increase to strong and temperatures will be a little cooler than Saturday.  Another pulse of snow is forecasted as early as Monday night.

Snowpack Summary

Wind slabs are developing below alpine lee ridge lines with gusty moderate West winds.  In sheltered areas, the recent storm snow has settled and bonded well.   Expect a suncrust on southerly treeline aspects and  widespread suncrust over the recent storm snow at lower elevations.

Avalanche Summary

Heli bombing had good results on the settled pockets of storm slabs above the Maligne Road on the Medicine Slabs.  No other activity was noted or reported but expect that a few small solar initiated slides occurred on steep south facing slopes below treeline on Saturday.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday
