Avalanche Summary

A few small loose dry avalanches were observed or triggered in steep, north-facing terrain on Friday.

No persistent slab avalanches have been reported since early February.

If you are traveling in the mountains consider posting to the MIN.

Snowpack Summary

A surface crust may exist on steep solar aspects. 10 to 15 cm of recent snow has been redistributed by moderate southerly wind. It sits over firm wind-affected surfaces in exposed areas or softer, faceted snow in sheltered terrain.

A weak layer of facets and a crust from early December is buried 60 to 100 cm deep. This layer exists on all aspects up to 1750 m. This layer has not been active in producing avalanches or test results in several weeks and is generally not a concern at this time.

At the highway elevation, the snow depth is 120 cm, and in the alpine exceeds 200 cm.

Weather Summary

Monday night

Partly cloudy with a trace of snow. 20 to 40 km/h southeast ridgetop wind. Treeline temperature -5 °C.

Tuesday

Mainly cloudy with 1 to 5 cm of snow. 50 to 70 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Wednesday

Cloudy with 3 to 8 cm of snow. 40 to 60 km/h southeast ridgetop wind. Treeline temperature -3 °C.

Thursday

Cloudy with 5 to 10 cm of snow. 60 to 80 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level rising to 1200 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
