Avalanche Summary

A couple of large cornice failures were observed last week in high alpine north-facing terrain. These loads notably did not propagate any weak layers on the slopes below.

Snowpack Summary

A dusting of new snow falls over widespread crusty surfaces on all but high north-facing alpine terrain, where snow is dry and likely wind affected. There are no deeper concerns at this time.

Weather Summary

Tuesday night

Partly cloudy. 20 to 30 km/h southwest ridgetop wind. Treeline temperature +2 °C. Freezing level 2200m.

Wednesday

Mostly cloudy with flurries bringing 5 to 10 cm. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1900m.

Thursday

5 to 15 cm overnight then a mix of sun and cloud. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1900m.

Friday

A mix of sun and cloud. <10 km/h east ridgetop wind. Treeline temperature +1 °C. Freezing level 2200m.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Wind Slabs

Small wind slabs are possible where wind has deposited sufficient snow into lee terrain features at upper elevations. Wind slabs may be especially reactive where they sit over a crust.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
