In sintesi

Typical Rockies snowpack with better than typical travel and good turns in north and east TL aspects.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2
    Northerly winds reverse loading cross-loaded gulley features. Previous wind slab from SW winds appear to be well bonded to snow below.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    This weak layer exists below a strong mid-pack at treeline and sub-alpine elevations. Large loads such as surface slides or cornice collapse could trigger this deep persistent weakness.

Weather Forecast

Cold with only a light teasing of new snow expected to fall in the southern forecast area.

Snowpack Summary

Consistent winds, just at transport speeds are forming minor new wind slabs by reverse loading S-SE aspects and are most visible in cross-loaded gully features in the southern forecast area. Shallow low density upper snowpack over a strong mid-pack sitting on a weaker facet base. Typical Rockies snowpack we've learned to love! Enjoy!

Avalanche Summary

No new avalanche activity reported in forecast area
