Lo esencial

Amazing ski quality at the moment on shaded aspects. Wind effect at this point is very isolated to ridge top and cross loaded features. The sun is really starting to pack a punch, Carefully evaluate solar aspects if you choose to ski them.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2

    Minimal wind effect noted on terrain travelled today up to 2600m.

  • Persistent Slabs

    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1.5–2.5

    Carefully evaluate the bond of the new snow to the underlying crust. Steep solar aspects and unsupported terrain should be carefully considered or avoided. Intense solar input will make this problem much more reactive.

Weather Forecast

Clouds are moving in for Monday. Day time highs around -6 with no snow expected. Winds should be fairly light in the valley's and pick up once in exposed alpine terrain.

Avalanche Summary

A wide spread Loose dry cycle out of unskiable steep alpine terrain was noted today. None of these produced a slab avalanche. 

Snowpack Summary

Saturday night delivered about 10cm. Brings the total storm snow amount to 40-50cm. This snow is very low density below 2600m.This is settling fast with the warm temps. High likelihood of a sun crust starting to form on steep solar aspects at treeline elevations. This is sitting on top of a variety of surfaces. Sun crusts on steep solar and hard wind slabs on all other aspects. The bond seems to be improving with the warm temperatures. 

Terrain and Travel

  • Be alert to conditions that change with elevation and wind exposure.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
