Highlights

Light snowfall amounts forecasted; only to be spoiled by strong surly winds blowing it around. Look to sheltered tree line areas for the best turns.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Quite variable but generally well bonded soft slabs and windslabs in lee features in the alpine and at treeline. Not likely to see much in natural activity but may be possible to trigger underfoot.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–3
    Large cornices or surface avalanches are the likely trigger.

Weather Forecast

Continuation of Friday's weather; full cloud cover, moderate to strong SE-ly winds with some local variation, small inputs of snow and freezing levels will rise above 2000ms. Despite mild temperatures, brisk winds and minimal solar influence should keep the surface dry and anything new available to transport will continue to load lee features.

Snowpack Summary

Still no significant change in snow or sun so little modification to the danger. Local variations though forecast area (near townsite) with significant rising daytime temps, freezing levels or snow inputs will weaken the bond on the storm slab at the surface on steeper slopes, especially on solar aspects or lower elevations.

Avalanche Summary

Field reports found no new activity to report.

Confidence

Timing, track, or intensity of incoming weather system is uncertain
