Lo esencial

A small refresh of snow is forecasted for tomorrow. This will bury sun crusts on solar aspects up in to tree line. As we start the transition in to the spring season. Timing is very important. Plan accordingly and finish early.

Problemas de aludes

  • Wind Slabs

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

    New snow and wind will build fresh wind slabs that overlie previous wind slabs. This all sits on top of the Feb 20th facet interface.

  • 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

Wednesday will see up to 5cm of snow with moderate winds.

Thursday will be a mix of sun and cloud with cold lows -18 warming to -8 during the day

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

Field teams down south today noted no new avalanche activity today.
