Highlights

Recent snow accumulation and wind loading have formed fresh slabs. Seek conservative terrain choices that avoid north-aspect terrain.

Avalanche problems

  • Wind Slabs

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

    Continued wind and available snow has formed wind slabs in areas just below ridgetops, at the top of gulleys, and at the base of steep features.

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1.5–2.5

    Expect new and weak cornice formation at ridge tops and at the top of gulleys.

Avalanche Summary

No new avalanches have been reported or observed.

Snowpack Summary

New accumulations between 10 cm and 15 cm overlie a thin snowpack. Upper elevation terrain in the direct lee of the past south wind harbors pockets up to 50 cm to 70 cm in depth with upper Alpine terrain nearing 100 cm in depth.

Coverage is minimal with many early seasons hazards such as thinly buried rocks and trees, open creeks, and weak lake ice.

Expect wind-transported snow to have formed wind slabs in the immediate lee of terrain features. Exposed upper windward terrain will continue to remain stripped down to old surfaces.

Weather Summary

Friday Night

Cloudy with snowfall, accumulation 1 cm to 5 cm, 60 km/hr southwest, alpine temperature -10 C, freezing level descending to sea level. Expected snowfall amounts in the white pass zone are to be on the high end of the forecast amounts.

Saturday

Cloudy with very light snowfall, accumulation trace amounts, 10 km/hr Northwest wind, alpine temperature -15 C, freezing level sea level.

Sunday

Cloudy with very light snowfall, accumulation trace amounts, 30 km/hr northeast wind, alpine temperature -18 C, freezing level sea level.

Monday

Cloudy with snowfall, accumulation trace amounts. 20 km/hr northeast wind, alpine temperature -20 C, freezing level sea level.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Uncertainty is best managed through conservative terrain choices at this time.
