Potential for small avalanches in the wind slab to step down to the Deep Persistent Weak Layers.

Confidence

High

If you're out in the hills, don't forget to post to the MIN. Every bit of information helps!

Snowpack Summary

Maligne valley received a trace of snow and overall remains unsupportive with less depth than the Icefields. There is a crust below 1800m. A layer of surface hoar and facets is down 20-40cm in sheltered areas. Large facets and depth hoar comprise the bottom portion of the snowpack.

Weather Summary

Monday is expected to be cloudy and flurries, -7 °C, and light Southwest winds. Tuesday will be very similar. Wednesday will have more sun and -10 °C. Thursday will be a mix of sun and cloud, -5 °C, and light winds. There maybe a temperature inversion.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

Avalanche Problems

Deep Persistent Slabs

The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3

Wind Slabs

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
