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

If there is a thick crust, avalanches are unlikely.

Spring conditions can change rapidly. Read about the 4 likely scenarios here.

Confidence

Low

Avalanche Summary

No new avalanches have been reported since the weekend, however, data is limited.

On Friday, skiers remotely triggered a slab on a northeast lee ridge feature at treeline near Mt. Fisher.

Snowpack Summary

5 to 15 cm of snow sits on a crust up high or moist snow below 2000 m. High alpine north facing slopes may still hold dry snow above a thick crust from late March.

The snowpack is quickly disappearing below treeline.

There are no other layers of concern.

Terrain and Travel Advice

  • Avalanche danger will increase as the surface crust breaks down.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Loose Wet

Wet loose avalanches are likely when there is no crust present.

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

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5

Cornices

Cornices may fail with warm temperatures and sunshine.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1.5 - 2.5
