Regions: Akamina, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West, South Rockies.

New low-density snow is available for transport. Human-triggered avalanches are possible. Assess often for signs of instability like shooting cracks as you transition into open terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches reported.

Suspect new low-density storm snow to be redistributed by westerly winds throughout the day building wind slabs in lee terrain features.

Snowpack Summary

Roughly 10 to 15 cm of new snow has buried various surfaces of wind-affected snow, thin sun crusts, and soft snow. These upper layers have bonded well to a widespread supportive crust that is down 20 to 40 cm.

Below this crust, the shallow faceted snowpack is moist and starting to refreeze with cool temperatures. Two crust layers, one in the midpack and another near the base of the snowpack continue to be monitored. Avalanches on these layers are unlikely.

Weather Summary

Friday Night

Clear with cloudy periods. Alpine wind southwest 15 to 20 km/h. Treeline temperature -10 °C.

Saturday

Mostly clear. Alpine wind southwest 20 to 30 km/h. Treeline temperature -10 °C.

Sunday

Mainly cloudy with scattered flurries with 2 to 5 cm accumulation. Alpine wind southwest 15 to 20 km/h. Treeline temperature -7 °C.

Monday

Mainly cloudy with scattered flurries with 2 to 4 cm accumulation. Alpine wind southwest 15 to 20 km/h. Treeline temperature -7 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.

Avalanche Problems

Wind Slabs

15 to 20 cm of new low-density snow is available for transport. increasing winds from the southwest will redistribute new snow into reactive wind slabs in lee terrain features at alpine and treeline elevations.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
