Lo esencial

Low hazard does not mean no hazard.

Winter snow may still be encountered in the high alpine, travel accordingly.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–1.5

    Lingering wind slabs may still be triggered in steep alpine terrain. Assess the snowpack as you go, looking for these stiff deposits of snow.

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1.5–3.5

    Be aware of large cornices overhead, or as you approach/walk along ridgelines. There were a few close calls last week, with people getting too close and luckily not being taken with the collapsing mass of snow.

Avalanche Summary

There were a few small avalanches in extreme north-facing terrain in the highway corridor on Friday and no new reported on Saturday

Last Sunday there was one skier accidental Sz 1.5 on Youngs Peak and a close call from a natural Sz 2 on Ursus Minor.

Cornices remain a concern with two close calls last weekend on Youngs Peak and along the ridgeline of Cheops

Snowpack Summary

Below treeline, you will find a well-settled spring snowpack, with a strong surface crust that may break down during the heat of the day.

The treeline snow depth is a record low of ~210cm. A variable crust exists on all but high northerly aspects, which may still hold dry snow.

The Feb 3rd crust/facet layer persists at upper elevations, buried 80-140cm down.

Weather Summary

Stable weather ends Monday as a weak frontal system arrives.

Tonight: Cloudy, clear periods. Alpine Low -7 °C. Freezing level (FZL) 1300m. Light W ridge wind.

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be carefull around freshly wind loaded features.
  • Remember that the snowpack will be significantly different at higher elevations than lower down.
