Regions

Glacier.

The latest storm dropped 50cm of snow onto a notable weak layer. Strong winds have moved this new snow around, creating cohesive storm slabs ripe for human triggering.

Check the storm interface on smaller, supported slopes while exploring conservative lines.

Confidence

Moderate

  • Forecast snowfall amounts are uncertain.

Avalanche Summary

Artillery avalanche control has been excellent today, with numerous sz 3-3.5 avalanches moving very fast into the valley bottoms.

Field teams in the past 2 days observed a soft storm slab at all elevations. This was reactive in steep or unsupported terrain features where there was wind effect (a stiffer surface).

Neighbouring areas are reporting easy to trigger storm slabs in the size 1- 2.5 range, failing on the surface hoar or suncrust (aspect depending) down 20-50cm.

Snowpack Summary

Up to 50-70cms of storm snow has fallen with moderate Southwest winds. This storm snow has buried a spotty layer of surface hoar in sheltered areas at treeline & below. On solar slopes the storm snow buries a suncrust.

There are no persistent weak layers in the mid or lower snowpack.

Weather Summary

Tonight Flurries, 10-15 cm. Alpine Low -10°C. Ridge wind SW 30-55 km/h. Freezing level (FZL) 600m.

Wed Scattered flurries, 5 cm. Alpine high -11°C. Wind SW 30-45. FZL 500m.

Thurs Flurries,10cm. Alpine High -12°C. Wind SW 35-65km/h. FZL Valley Bottom.

Fri Scattered flurries, 5cm. Alpine high -9°C. Wind W 30-40km/h. FZL 1000m

Terrain and Travel Advice

  • Don't let the desire for deep powder pull you into high consequence terrain.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Carefully manage your exposure to overhead hazards.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
