Highlights

Good skiing can be found at elevations over 1700m. Evaluate snow and terrain carefully for changing conditions.

Expect open water BTL and plan your travel accordingly. 

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    Recently formed wind slabs can be found in lee features near ridge crests, and in cross-loaded gullies.

  • Loose Dry

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–1.5

    Enough new snow has fallen over the past few days to produce Loose Dry avalanches in steep terrain. Use caution in exposed or confined features where small avalanches can have high consequences.

Weather Forecast

The next few days will see varied conditions though the region. Winds will increase to 40-60 km/h, SW at ridge tops. Light precip, in many forms can be expected. In addition, freezing levels forecast to remain near valley bottom overnight, rising to 1500-1800m.

Wednesday: Cloudy with scattered flurries, up to 5cm. Alpine temperature: High -4 °C.

Snowpack Summary

Convective flurries and favorable SW winds have redistributed low density, new snow over hard windslab and varied crusts at TL/ALP elevations. This combination often creates a very poor bond at the interface and users should be wary of isolated slab development in open and/or steep features. Difficult travel BTL, w/ covered hazards and open water.

Avalanche Summary

No new avalanche activity observed or reported today.
