Regions: East Kakwa, Kakwa, McGregor, North Rockies, Pine Pass, Renshaw, Robson, Sugarbowl, Tumbler.

Continuously assess and verify conditions as you move through the mountains

Recent snowfall amounts are highly variable, we have uncertainty in both the size and likelihood of avalanches

Confidence

Moderate

Avalanche Summary

One size 1 skier triggered storm slab avalanche was reported on Sunday. This avalanche was 60 cm deep and ran on a small but steep north facing treeline feature.

On Saturday, a small natural wind slab avalanche was observed in the PK backcountry, check out this detailed MIN for more info.

Observations in the region were limited over the weekend. More avalanche activity could have taken place.

Snowpack Summary

Recent snowfall amounts in the region are highly variable,  15 to 60 cm has fallen with moderate southwest winds, forming deeper deposits on north and east aspects. This new snow overlies a crust on all aspects and elevations except north facing slopes above 1400 m. In isolated locations surface hoar could also be found at this interface.

A weak layer of surface hoar or facets from mid February is found 40 to 100 cm down.

The lower snowpack is well settled and bonded.

Weather Summary

Monday Night

Mostly cloudy with 0 to 5 cm of snow. 20 to 40 km/h south ridgetop wind. Treeline temperature -6 °C.

Tuesday

Clearing throughout the day with 0 to 5 cm of snow in the morning. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Tuesday

Mostly cloudy with around 5 cm of snow. 10 to 30 km/h southeast ridgetop wind. Treeline temperature -4 °C.

Wednesday

Mostly cloudy with around 5 cm of snow. 20 to 40 km/h northeast ridgetop wind. Treeline temperature -13  °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be careful as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Make observations and continually assess conditions as you travel.

Avalanche Problems

Storm Slabs

Storm slabs will likely remain rider triggerable. Assess new snow amounts, the more you find the larger and more sensitive slabs will be.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5

Persistent Slabs

The mid February layer could still be rider triggerable, especially where a thick crust isn't found above it.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1.5 - 3
