Highlights

New snowfall combined with rising temperatures will elevate danger levels.

A sharp increase in hazard is expected when precipitation changes from snow to rain.

    Triggering a small wind slab is still a possibility. Travel one at a time on steep slopes and watch your friends.

    Expect new snowfall and warming temperatures to create a storm slab problem. This new slab will overlie a variety of surfaces, including a thin sun crust on solar aspects and smooth, hard wind-pressed snow in wind-exposed areas.

Avalanche Summary

No avalanches have been reported. However, observations are limited.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

Above treeline, an estimated 20 to 30 cm of snow sits on a thick crust that extends to the ground. The snowpack is around 40 to 70 cm deep in the alpine, and shrinks rapidly below treeline.

In wind exposed areas, soft snow has likely been redistributed into lee features.

Weather Summary

Friday
Cloudy. 10 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

Saturday
Cloudy. 25 to 30 mm of precipitation as snow or rain at treeline. 40 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Sunday
Mostly cloudy. 35 to 40 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avalanche danger will rapidly increase if snow switches to rain.
  • Be cautious of buried obstacles, especially below treeline.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
