In sintesi

Strong winds will form small reactive windslabs throughout the day.

A widespread surface crust has created relatively stable avalanche conditions, but travel is challenging.

Avalanche Summary

No recent avalanche activity has been reported.

If you head out consider posting to the mountain information network.

Snowpack Summary

Up to 15 cm of dry snow has accumulated atop a widespread hard crust. In general, the crust is strong and supportive to travel on.

Currently, it's unlikely that any lingering weak layers deeper in the snowpack could be triggered due to the strong supportive crust above.

Last week's warm temperatures significantly melted the snowpack below the treeline and in shallow alpine terrain. See the North Rockies MIN post for photos of conditions in the Morfee area.

Areas in the east of the region are largely characterized by a shallow and faceted snowpack.

Weather Summary

Friday Night

Mostly clear, 30 to 40 km/h west alpine wind, treeline temperature -9 °C.

Saturday

Mostly cloudy with up to 5 cm of snow, 50 to 70 km/h west alpine wind, treeline temperature -3 °C.

Sunday

Mostly cloudy with up to 5 cm of snow, 40 to 60 km/h southwest alpine wind, treeline temperature -3 °C.

Monday

Mostly sunny, 30 to 40 km/h northwest alpine wind, treeline temperature -6 °C

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Expect shallow snow cover that barely covers ground roughness.
  • Wind slabs are most reactive during their formation.
