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

Cautious travel is advised.

Avalanche Summary

No new avalanches were reported on Wednesday or Thursday.

On Tuesday, a few large (size 2) storm slab avalanches were triggered with explosives by local operations.

Snowpack Summary

30-40 cm of soft snow sits on top of a crust from early November that's just above the ground. The crust may have weak, sugary facets on top, if this is the case large avalanches are possible.
Snowpack depths are expected to be 40-60 cm at treeline.

Terrain and Travel Advice

  • Use small, low consequence slopes to test the bond of the new snow.
  • Watch for fresh storm slabs building throughout the day.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Avalanche Problems

Storm Slabs

Give the new snow time to settle before moving into steep terrain. The new snow might not bond well to the crust near the bottom.
