Lo esencial

The Tonquin Area is officially open for winter travel. Use caution as this area is typically more shallow and therefore a weaker snowpack. Be vigilant for shallow locations being human trigger spots.

Problemas de aludes

  • Wind Slabs

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

    Moderate to strong SW winds in the alpine and higher RH values are likely creating wind slabs.

  • Loose Dry

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

    The likelihood of triggering increases with warming temperatures and solar input. Isolated, sheltered features that have not been impacted by winds are susceptible to sluffing and loose dry avalanches. Ice climbers be aware of these features.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely
    Tamaño
    1.5–3

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

Weather Forecast

Thursday will be a mix of sun and cloud, -12 C and light SW winds.  Friday will bring sun and cloud with isolated flurries, -10 C, and light gusting moderate SW winds.

Snowpack Summary

Moderate to strong SW winds and higher humidity continue to create wind slabs in high alpine lee features. The upper snowpack has facetted from the recent cold temperatures and overlies a supportive mid-pack, except in shallow areas where the entire snowpack is weak and facetted.

Avalanche Summary

Wednesday's patrol was cut short due to a rescue. Nothing new was noted or reported.
