Lo esencial

Thursday is shaping up to be a great day to get out and get up high. Clear skies's and calm winds. Keep in mind the wind slabs that are out there are sitting on top of a weak layer (Facets)

Problemas de aludes

  • Wind Slabs

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

    Calmer winds are decreasing the reactivity of wind slabs. These sits on top of the Feb 20th facet interface.

  • Loose Wet

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

    As the mercury slowly rises above 0 and the sun comes out, solar slopes will start to loose strength. Caution with your timing when traveling on/under these features.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–3

    Caution in thin facetted snowpack areas where triggering is more likely. This is a low probability but high consequence problem.

Weather Forecast

No precip expected over the next several days.

High -9 lows -13 for Thursday

Winds will be generally light out of the west

Snowpack Summary

High solar input have created crusts and moist snow on solar aspects at TL and below. Continuing SW winds have extensively redistributed the snow pack at TL and ALP. The mid pack is supportive in deep areas, but shallow snowpack areas are weak and failing on buried facet layers in test results.

Avalanche Summary

No field teams or avalanche report today
