Highlights

Although natural avalanches are unlikely right now, human triggered avalanches are still possible. Be cautious around shallow areas in big terrain, where the consequence of triggering an avalanche would be serious.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–3
    Cross loaded gullies may be the most attractive after the intense wind scouring in the alpine, but careful evaluation is essential to check for the presence of reactive windslabs.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–3
    Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.

Weather Forecast

Mild temperatures through to the end of the week, freezing level to 2000m on Friday. Winds to remain light from the West. No new precipitation expected until the middle of next week.  Partly cloudy skies, clearing towards the weekend.

Snowpack Summary

Shallow and weak snowpack sits on 10-20cm of basal facets. Midpack hard slabs provide bridging above treeline and into the alpine. Extensive scouring at upper elevations. Surface hoar growth observed in the last few days up to size 5mm below treeline and up to size 3mm above treeline.

Avalanche Summary

No new avalanches observed or reported.
