In sintesi

Expect avalanche hazard to rise with forecast flurries and wind. Check for loaded pockets around ridgelines and assess steep slopes for dense or stiff snow before committing.

    Accumulating flurries and gusty winds will form reactive deposits. Check for wind slabs in lee features and cross-loaded slopes at higher elevations.

    Dry loose sluffing may exist in steep terrain features.

Avalanche Summary

No new avalanches reported. If you are out and about in the mountains, please consider posting your observations to the MIN.

Snowpack Summary

At treeline and above, 8–12 cm of new snow sits on top of faceted snow or surface hoar. The upper snowpack is mixed: wind-affected in open areas and softer in sheltered spots, all sitting on the mid-November crust buried 30–50 cm deep. Lower in the snowpack, there are several crusts, and in some areas a weak, sugary facets can be found near the ground.

Total snowpack depths are roughly 80 to 120 cm, tapering quickly at lower elevations.

In many areas, especially below treeline, there is not enough snow to smooth out surface roughness or reach the threshold needed for avalanches.

Weather Summary

Thursday Night

Mostly cloudy. 15 to 25 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Friday

Cloudy with 5 to 15 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -6 °C.

Saturday

Mostly cloudy. 5 to 10 cm of snow. 15 to 30 km/h west ridgetop wind. Treeline temperature -8 °C.

Sunday

Mix of sun and clouds. 5 cm of snow. 10 to 20 km/h west ridgetop wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be cautious of buried obstacles, especially below treeline.
