Human-triggered avalanches are possible.

Use safe travel habits and regroup in safe spots.

Confidence

Moderate

Avalanche Summary

On Tuesday one small (size 1) slab avalanche was triggered by a skier on a northeast aspect in the alpine. Two small slabs and one very large (size 3) avalanche were triggered by explosive control work. On Monday a very large (size 3) natural avalanche was reported near Valemount.

Obvious signs of instability are tapering off, but human-triggered avalanches are still possible.

Snowpack Summary

Up to 20 cm of snow has fallen since Monday. This new snow overlies a melt-freeze crust on sun-exposed slopes.

Three persistent weak layers of surface hoar and/or facets are found in the middle of the snowpack. The early March layer is between 60 and 120 cm down. The mid-February layer is between 70 and 150 cm deep and a layer from late January is down 150 cm. In lower elevations, these layers sit over a crust.

Below this, the snowpack is well settled.

Weather Summary

Wednesday night

Cloudy with 0 to 5 cm of snow. 30 to 40 km/h south ridgetop wind. Treeline temperature -6 °C.

Thursday

Cloudy with 2 to 10 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Friday

Mostly cloudy with 0 to 5 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Saturday

Mostly cloudy with 0 to 5 cm of snow. 20 to 30 km/h west ridgetop winds. Treeline temperature -6 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Be especially cautious as you transition into wind-affected terrain.

Avalanche Problems

Storm Slabs

Moderate winds have created wind slabs in the alpine and treeline elevations. These could step down to deeper persistent weak layers.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1.5 - 2.5

Persistent Slabs

It remains possible that humans could trigger surface hoar and/or faceted grains that were buried early March and mid-February, especially at high elevations where a thick crust doesn't exist above it.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 3
