Highlights

Very little change happening to the snowpack.

Continue to maintain a DEEP skepticism and PERSISTENT margin of safety when pushing into new or unfamiliar terrain.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2.5

    Wind slabs are widespread in the alpine on lee and cross-loaded features. Triggering has the potential to initiate the deep persistent slab

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1.5–3.5

    Skier triggering could occur in shallow snowpack areas or from large loads such a cornice failure. The consequences of triggering would be severe!

Weather Forecast

A trough, developing over the eastern front ranges will draw moderate to strong westerly gap winds (20km/h, gusting to 45 km/h) over the Parkway on Wednesday. Alpine High temperature, -7.
