Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    Northerly winds reverse loading cross-loaded gulley features and South sides of ridge crests.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    This weak layer exists below a strong mid-pack at treeline and sub-alpine elevations. Large loads such as a cornice collapse could trigger this deep persistent weakness. The cold temperatures will be having a facetting effect on shallow locations.

Weather Forecast

The weather forecast is calling for increasing clouds through Thursday with snow beginning on Thursday afternoon and continuing into the weekend. Temperatures will be gradually warming (comparatively speaking) to around -10 for the daytime highs on the weekend. Winds will shift to a Westerly direction overnight.

Snowpack Summary

North winds are forming new wind slabs by reverse loading S-SE aspects near ridge crests and cross-loaded gully features. A Shallow low density upper snowpack sits on a strong, supportive mid-pack which is bridging a weaker facet base.

Avalanche Summary

No new avalanche activity reported in the forecast area.

Confidence

Intensity of incoming weather systems is uncertain on Thursday
