Update 6:10 AM

Continue to make conservative terrain choices while the storm snow settles and stabilizes.

    Warm temperatures and light rain continue to promote wet loose avalanche activity at treeline and below.

    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

Reports on Friday indicated numerous small to large wet loose sluffs and slab avalanches up to size 3 in the north of the region. Reports from areas near Terrace were limited, likely due to poor visibility, with several small loose wet sluffs observed at lower elevations.

While precipitation is expected to remain light through Sunday, the danger is expected to remain elevated with large natural avalanches possible and human-triggering likely.

Snowpack Summary

30 to 80 cm of settling storm snow has fallen since Monday, accompanied by rain at lower elevations. Another 5 to 15 mm of rain or snow at treeline is expected by the end of day Sunday. This storm snow will be heavy, and wet below the rain line. Above the rain line, the snow surface has seen widespread wind effect in open areas from strong southwesterly winds.

In many areas, the storm 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.

Monday

Cloudy. 15 to 30 mm of precipitation as snow or rain at treeline. 50 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1400 m.

Tuesday

Cloudy. 10 to 25 mm of rain at treeline. 60 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level rising to 1800 m.

More details can be found in the Mountain Weather Forecast.

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.
