Lo esencial

Cornices are beginning to weaken and there have be a number of close calls in neighboring forecast areas.  Stay well back from corniced ridge lines.

Problemas de aludes

  • Wind Slabs

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

    Probabilidad

    Tamaño

    Loose snow avalanches are likely on steep thin slopes and in gulley features.  Loose snow avalanches are possible on all aspects, however, solar triggering is most likely.

Weather Forecast

Clearing overnight with clouds moving back in Saturday afternoon.  No precipitation is expected in the next 24 hours and winds will be light from the northwest. Seasonal temperatures are forecast, slightly cooler overnight.

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 the snow depth 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.
