Avalanche Summary

No new avalanche reports. Keep sharing your observations via the MIN; it helps strengthen our information gathering.

Snowpack Summary

In deeper zones at 1900 m the snowpack is around 100-130 cm, which is low for middle of December, and it has a weak structure.

Surface: Boot top powder in deep areas. Same old crusts, facets, and rocks on wind scoured slopes. Wind slab pockets lee of ridges.Upper-pack: Below the fresh snow is well developed surface hoar in sheltered areas. The uppper part of the snow pack is generally low density and faceting (aka weak).Mid-pack: maybe a crust or two, with a layer of soft facets above. This is likely the primary weak layer.Lower-pack: facets and depth hoar (aka not strong).

Weather Summary

Saturday NightCooling temperatures with freezing level falling from 900m to around 500m. Dry. South or SW wind moderate but diminishing.

SundayDry. Temps between -5 and close to 0 C. Freezing level around 500 m. Light wind. Mostly cloudy.

Monday

Dry. Cooler with temps between -5 to -10 C and freezing level to valley bottom. Northerly light wind with outflow from the interior through the passes and in the major valleys. Mix of sun and cloud but generally clearing.

Tuesday

Similar to Monday but more sun and less cloud.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Expect shallow snow cover that barely covers ground roughness.

Avalanche Problems

Wind Slabs

Watch for pockets of cohesive wind slabs on the lee side of ridges or ribs. However, with the sugary-faceted-weak snowpack avalanches could step down to the middle of the snowpack.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
