Regions: Glacier.

An incoming storm will bring new snow, warm temps and increased winds.

As the storm progresses the avalanche danger will rise.

Confidence

Moderate

Weather Summary

An active weather pattern is developing with a juicy storm on the horizon.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.

Avalanche Problems

Storm Slabs

Fresh snow and moderate to strong winds will be creating a new slab. This will be sitting on (yet another) weak layer of facets, expect this to be most reactive in immediate lee features. As the storm progresses the storm slab will become more widespread and reactive.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2.5

Persistent Slabs

20-50cms of snow overlays a buried persistent weak layer. This weak layer consists of surface hoar, facets and/or a suncrust. It will be most reactive where there is a settled, cohesive slab on top of a crust.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
