In sintesi

We have a highly variable snowpack.  Good avalanche hazard evaluation skills are needed to travel on this landscape.   

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–3
    Wind slabs can be found above tree line in exposed terrain. These slabs have been unreactive to skier traffic, however, it is still possible to trigger a slab in steep unsupported terrain.

  • Loose Dry

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2
    Loose snow avalanches are likely on steep thin slopes and in gulley features.  Although these avalanches are possible on all aspects, solar triggering is most likely.

Weather Forecast

Expecting temperatures to cool slightly with broken skies predicted on Friday.  A skiff of snow is possible and alpine winds will blow strong from the West.  Only light westerlies are forecast at lower elevations.

Snowpack Summary

The snowpack is faceting and losing strength especially in shallow areas.  At tree line and above, the mid-pack is generally supportive where snow pack is greater than a meter.  Wind slabs are present in lee features at upper elevations. Surface hoar is developing with the cool overnight temperatures and light valley bottom winds.

Avalanche Summary

No avalanches reported today though expect some loose snow sluffing on solar aspects.
