Lo esencial

The October layer of facets/depth hoar/crust has been associated with 6 avalanche involvements so far this season! This layer is here to stay and should be an important consideration in route selection.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Wind slabs are found in the Alpine and open areas at Treeline. No recent natural avalanches have been associated with this problem, but human triggering is still possible, especially along ridge crests or in steep and unsupported terrain.

  • Persistent Slabs

    Avalanches could step down to the basal October crust (or the ground) and involve the entire winters snowpack, especially in shallow snowpack areas. Some whumpfing has been experienced in recent days.

Confidence

Good

Weather Forecast

Mainly cloudy with a only trace amounts of precipitation expected over the next several days. Winds will be strong from the West and Alpine temperatures are expected to be in the -7 to -15 range.

Avalanche Summary

Nothing new observed or reported.

Snowpack Summary

Overall the snowpack is weak and facetted at lower elevations. At treeline and above wind slabs are present in lee and cross-loaded features. In addition, concern remains for the October facet/crust/depth hoar layer. Whumpfing has been observed in recent days and confidence is low in the integrity of this layer.
