Lo esencial

The forecast suggests a stabilizing trend, but stay tuned in for the trouble layers. Local conditions may vary from place to place.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–3
    The distribution of this layer is largely unknown. It is worth hunting for it in a few areas to track it before committing to your line. Dig deeper than normal for a thorough inspection.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    This problem is easily tracked and assessed. Open areas at treeline are more suspect.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–4
    This weak basal layer is everywhere. Caution in thin areas, and/or areas with a rocky base.

Confidence

Fair - Due to the number of field observations on Tuesday

Weather Forecast

Alpine temps will rise tomorrow. They will settle into the -10 to -8 range by tomorrow afternoon. Winds will be out of the NW and generally moderate. No new snow is expected.

Avalanche Summary

Limited observations today.

Snowpack Summary

No new snow today. The buried surface hoar layer is a concern. Its depth varies considerably from area to area. At treeline, it may be down as much as 30cm. The two other persistent problems are deeper, but not as concerning at the moment. The Dec 13th will be down 60cm at treeline and the Nov 6th will be just above the ground. Average snow depths range from 60cm at valley bottom to 110 at treeline.
