The deep freeze is finally leaving, bringing sunny skies and pleasant temperatures.

Be cautious as you step outside again, the snowpack has only become weaker with the long cold spell.

Avalanche Summary

Numerous deep persistent slabs up to size 2.5 have been observed in the alpine over the last few days.

Loose dry avalanches up to size 2 in very steep rocky alpine terrain were noted over the past few days. Some are scrubbing to ground.

Terrain and Travel Advice

  • Loose avalanches may start small but they can grow and push you into dangerous terrain.
  • Be carefull around freshly wind loaded features.

Avalanche Problems

Wind Slabs

The previous northerly winds have created winds slabs which are decreasing in sensitivity

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

A handful of loose dry avalanches have occurred recently with one scrubbing to ground. They are currently limited to specific terrain such as very steep alpine rocky terrain yet enough of a concern if a person is standing below it or gets swept away.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Likely

Expected Size: 1 - 2

Deep Persistent Slabs

You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2.5
