In sintesi

The snow cover is presenting several avalanche problems that are quite elevation dependent.  Pay attention to changing conditions as you move through the hills.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    Recent winds have created a slab condition in the alpine. Cornices are growing and we observed two cornice triggered avalanches today. 

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2
    The recent storm snow, redistributed by wind is now over loading the snowpack. Several skier remote avalanches were observed today.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Expect the avalanche danger on sheltered solar aspects to be suspect during the heat of the day. 

Weather Forecast

Strong south westerly winds and light precipitation are expected for the next 24 hours.  Temperatures are expected to be mild, with above freezing temperatures in valley bottom locations and on sheltered southerly aspects.

Snowpack Summary

Gusty winds at all elevations and mild temperatures have lead to a touchy slab condition at tree line and in the alpine. The surface condition is now a stiff wind slab on exposed slopes.

Avalanche Summary

Several remote triggered avalanches were observed in the Parker Ridge and Hilda Creek area today. These stiff slabs were easily triggered from adjacent slopes. Two cornice release triggered slabs that stepped down to ground on steep rocky faces in the alpine today.
