Avalanche Summary

There are no recent avalanche reports for this region.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

New snowfall will begin to bury existing surface hoar that was previously found in wind-sheltered, and sun-sheltered open terrain. A thin melt-freeze crust may exist on south-facing slopes.

Above 1800 m on non-solar slopes, you can find 10 to 30 cm of snow above a thin crust. The crust disappears as you travel higher into the alpine.

Below 1800 m, 5 to 15 cm of snow sits overtop a thicker and more robust crust.

Snow depths at treeline are around 70-80 cm.

Weather Summary

Friday Night

Snow 5 to 10 cm. 20 to 25 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Saturday

Snow 5 to 15 cm. 15 to 30 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1200 m.

Sunday

Snow 1 to 2 cm. 10 to 25 km/h southeast ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

Monday

Snow 2 to 5 cm. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Be aware of the potential for large avalanches due to buried surface hoar.

Avalanche Problems

Storm Slabs

Buried surface hoar in sheltered terrain is expected to become increasingly reactive to human triggers. Wind slabs will form at high elevations where new snow has been loaded into leeward features.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
