The sun will be out and the freezing level is forecast to be higher than it has been in the past few days. As a result there may be an increase in wet loose avalanche activity on steep terrain facing the sun.

Confidence

High

Avalanche Summary

On Tuesday there were several reports of loose wet avalanches running to size 1.5 in steep terrain facing the sun.

Snowpack Summary

Recent snow accumulated over the last week overlies a crust on all terrain except north-facing slopes treeline and above. On these high northerly slopes, new snow may overlie facets and surface hoar to mountain tops.

The mid-pack is generally well-settled.

The lower snowpack includes a layer of weak sugary facets near the ground. These facets are slowly gaining strength and no recent avalanches have been reported on this layer. However, we continue to track the layer and watch for any signs of it becoming active.

Terrain and Travel Advice

  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Avalanche Problems

Loose Wet

The sun may be out for extended periods so expect to see an increase in thin loose wet avalanche activity on steep terrain facing the sun.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
