Tune in to the changing conditions of elevation, aspect, and time of day.

Be cautious in wind-affected terrain and avoid steep sun-exposed slopes and overhead hazard during periods of strong sun.




Avalanche Summary

Small (size 1) wet loose avalanches have been observed throughout the week during periods of strong solar radiation.

On Sunday, a rockfall triggered a large (size 2.5) wet loose avalanche on a southwest aspect in the alpine. A natural cornice failure was observed but it did not pull a slab on the slope below.

Snowpack Summary

Cool, clear weather has promoted surface faceting and surface hoar growth. A crust exist on the surface on all aspects below 1800 m and steep south facing slopes.

At treeline and below, a weak layer of rounding surface hoar is found 20-50 cm down in sheltered terrain. No recent reactivity has been observed on this interface.

The lower snowpack is well consolidated and strong.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.


Wind Slabs

An icon showing Wind Slabs

Easterly wind may have redistributed the surface snow into fresh pockets of wind slab in the alpine.

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

Elevations: Alpine.



Expected Size

1 - 2

Loose Wet

An icon showing Loose Wet

Warm temperatures and strong sun may create wet loose avalanche on steep sun exposed slopes.

Keep in mind, that wet loose avalanches may start small but they can grow and push you into dangerous terrain.

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

Elevations: All elevations.


Possible - Likely

Expected Size

1 - 2
