Assess for slab properties as you move through terrain.
Rider triggerable slabs are possible where a slab overlies facets, surface hoar or a crust.

Terrain and Travel Advice:
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Persistent Slab

New snow will add to the load over weak layers from early February and late January.

Wind Slab

New snow and wind will form wind slabs near ridge crests.

Avalanche Summary

Over the past week we have seen a pattern of human and remotely triggered size 1 to 1.5 wind slab avalanches with a few being up to size 2. Human-triggered avalanches have occurred on a range of aspects. Slabs have been averaging 20 - 30 cm thick, with some failing on buried surface hoar and propagating widely.

Snowpack Summary

Up to 20 cm of new snow could accumulate over a variety of surfaces including; a crust on south aspects and all aspects at lower elevation, Surface hoar in sheltered features and previously wind effected surfaces in exposed terrain.

30 to 40 cm of snow sits above large surface hoar and/or faceted crystals at treeline and above. This is most problematic in places where wind slabs have formed over it. A widespread, supportive crust exists 30 to 60 cm below the surface. It is an excellent bed surface for slabs run to on.

The snowpack is well bonded and strong below this crust.

Weather Summary

Tuesday Night

Mostly cloudy with 5 to 10 cm of new snow expected. 15 to 30 km/h south alpine wind. Treeline temperature -2°C.

Wednesday

Mostly cloudy with 5 to 10 cm of new snow expected. 15 to 30 km/h southeast alpine wind. Freezing level rising to 1700 m.

Thursday

Mostly cloudy with around 5 cm of new snow expected. 5 to 15 km/h southeast alpine wind. Freezing level rising to 1500 m.

Friday

Mostly sunny with trace amounts of new snow possible. 30 to 50 km/h southwest alpine wind. Freezing level rising to 1700 m.

More details can be found in the Mountain Weather Forecast.

Confidence: moderate
Uncertainty is due to the track & intensity of the incoming weather system.

Use caution in wind effected terrain, wind slab over facets, surface hoar or a crust remains the primary concern.

Terrain and Travel Advice:
  • Use ridges or ribs to avoid areas of wind loaded snow.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
Wind Slab

Winds have varied in direction over the past few days, wind slabs could be found on all aspects. These slabs will be most reactive where they overlie surface hoar and/or a crust.

Avalanche Summary

Check out this MIN with some recent avalanche observations.

Over the past week we have seen a pattern of human and remotely triggered size 1 to 1.5 wind slab avalanches with a few being up to size 2.  These avalanches have generally failed  on a combination of facets, surface hoar and a crust.

Snowpack Summary

Up to 10 cm of new snow could accumulate over a variety of surfaces including; a crust on south aspects and all aspects at lower elevation, Surface hoar in sheltered features and previously wind effected surfaces in exposed terrain.

Old wind slabs that formed over facets, a crust or surface hoar can still be found on south and west aspects.

15 to 40 cm of snow sits above a widespread crust from late January. Surface hoar may be found above this crust.

Snowpack depths decrease rapidly below treeline.

Weather Summary

Tuesday Night

Mostly cloudy with around 5 cm of new snow expected. 10 to 25 km/h south alpine wind. Treeline temperature -2°C.

Wednesday

Clearing sky throughout the day with up to 5 cm of new snow expected  in the morning. 10 to 25 km/h southeast alpine wind. Freezing level rising to 1700 m.

Thursday

A mix of sun and cloud with trace amounts of new snow expected in the morning. 5 to 15 km/h southeast alpine wind. Freezing level rising to 1500 m.

Friday

A mix of sun and cloud with trace amounts of new snow possible. 30 to 50 km/h southwest alpine wind. Treeline temperature -2°C.

Confidence: moderate
The snowpack structure is generally well understood.
