Regions: Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Jasper, Maligne, Marmot, Miette Lake, Pyramid.

Cool and stable weather with no significant precipitation for the next few days will contribute to lower avalanche danger.

Be cautious of surface snow sloughing off steep slopes above you, and enjoy some soft turns in the sun this weekend.

Snowpack Summary

About 10cm of new snow fell onto a 2-5cm melt freeze crust on Wednesday. The Feb 3rd crust interface is down 35-60cm. Basal depth hoar makes up the bottom third of the snowpack. HS ranges from 50 to 150cm.Sunday

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

Avalanche Problems

Loose Dry

Loose dry avalanches likely won't be much of a hazard unless they push you into or off a terrain trap.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5

Persistent Slabs

This problem layer is the crust and facets created by early February's warm spell. It is down 30-90 cm in the snowpack and is a 1-10 cm thick crust or multiple crusts with a layer of weak facets above.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1.5 - 3

Deep Persistent Slabs

Basal depth hoar makes up the bottom of the snowpack. This is a low probability but high consequence problem. Stay away from weak, rocky, shallow location where triggering this layer is more likely.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3.5
