Lo esencial

This is NOT the time to be in avalanche terrain. If you do head out, be very aware of the snowpack conditions as you travel. Use very small terrain features to test the snow and see how it reacts. MM

Problemas de aludes

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–3
    This is the main concern right now. The layer is not adjusting to the new load and is extremely touchy right now. Remote avalanches have been reported on this layer in a variety of areas.

  • Loose Dry

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–2
    Sluffing will be a problem in steeper terrain. These sluffs will likely trigger deeper layers.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    1–4
    These slabs are widespread at treeline and alpine elevations. Choose supported terrain and avoid terrain traps.

Weather Forecast

The snow is expected to stop tonight. The flow will swap to a northerly direction and of course the temps will fall with that swap. Saturday has clear skies forecasted with light winds.

Avalanche Summary

We had two remote avalanches today on our snow study trip. Both features were at treeline and on steep, unsupported rolls. The crust was the failure plain. Both avalanches were sz1. There was a surprising amount of sluffing on the few steeper turns we had.

Snowpack Summary

LOTS of new snow out there. We have had up to 55 cm's in the last few days. The winds haven't packed the punch that we expected, but windslabs, and settlement slabs are still widespread. As expected, the bond with the deeper layers is poor. The deeper layers consist of a facets and a variety of crusts. The most significant crust is the Nov 6th. which is up 10cm's from the ground and buried under 30-50cm's at treeline.
