In sintesi

Stick to conservative terrain, avoiding overhead hazard. Remote triggering of large avalanches may be possible at all elevations.

    Recent storm snow is overlying a reactive weak layer. Remote triggering is a possibility, avoid overhead hazard.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

A natural avalanche cycle to size 2.5 was observed in the north of the region, starting early Wednesday morning and was ongoing throughout Friday. Additional reports from Friday indicated numerous wet loose and wet slab avalanches up to size 3.

While precipitation is expected to taper off on Saturday, the danger is expected to remain elevated with large natural avalanches possible and human-triggering likely.

Snowpack Summary

30 to 100 cm of storm snow has fallen since Monday, accompanied by rain at lower elevations. This storm snow will be heavy, and wet below the rain line, which is estimated to reach 1500 m. Above the rain line, the snow surface has seen widespread wind effect from strong southwesterly winds.

In many areas, the recent snow is overlying a reactive weak layer of surface hoar or facets, over a thick, hard crust.

A deeper layer of surface hoar from early January can be found down 70 to 250 cm, and remains a lingering concern.

Treeline snow depths throughout the region range from 250 to 450 cm.

Weather Summary

Friday Night

Mostly cloudy. 0 to 4 mm of precipitation as snow or rain at treeline. 35 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m falling to 1000 m.

Saturday

Mostly cloudy. 0 to 4 mm of precipitation as snow or rain at treeline. 30 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1200 m.

Sunday

Mostly cloudy. 5 to 15 cm of snow at treeline, rain below. 40 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1300 m.

Monday

Mostly cloudy. 10 to 20 mm of rain at treeline. 45 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1400 m.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Keep in mind that the high density of wet avalanches can make them destructive.
