Avalanche Summary

A small wind slab was seen on Monday from a northwest facing slope at treeline.

Avalanche activity has tapered since the weekend, and so have the number of observations.

Snowpack Summary

Around 10 cm of recent snow redistributed by southerly wind lies over a crust that goes up to 1250 m in the shade and up to mountain top on slopes that get the sun. Good riding can still be found in sheltered slopes away from the sun.

The mid-pack is generally well settled, with crusts buried around 50 cm, and another near 130 cm deep.

The lower snowpack is facetted, but hasn't been a problem.

Below 1100 m the snowpack is wet and losing strength.

Weather Summary

Wednesday Night

Cloudy. 40 to 80 km/h south ridgetop wind. Treeline temperature -4 °C.

Thursday

Cloudy with 0 to 1 cm of snow. 50 to 90 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 800 m.

Friday

Mostly cloudy with 5 to 15 cm of snow. 30 to 40 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Saturday

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid freshly wind-loaded terrain features.

Avalanche Problems

Wind Slabs

Riders may trigger slabs in wind loaded areas. Strong wind may form new wind slabs.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Cornices

Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1.5 - 2.5
