In sintesi

Human triggering of wind slabs remains possible.

Continually assess as you travel. Identify wind-affected slopes, and back off if snow feel dense or stiff.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2

    Wind slabs have formed over previous surfaces of hard wind pressed snow or crust and are remain possible to human-trigger.

  • Persistent Slabs

    Persistent weak layers in the upper snowpack remain a concern for human triggering. Where there is no supportive surface crust, triggering these layers remains possible.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Reports of avalanche activity has tapered, no new avalanches reported.

Going forward, cold temperatures are likely to keep wind slabs possible to human trigger as they are slow to bond to hard wind pressed surfaces.

Snowpack Summary

Roughly 15 to 20 cm of new snow is being redistributed by moderate southwest wind. This cold new snow overlies previously wind-affected surfaces treeline and above, and at lower elevations a crust.

Two weak layers remain a concern:

  • A crust/facet layer buried early February down 90 to 120 cm.

  • A surface hoar layer buried mid February down 60 to 90 cm.

Recent avalanche activity has involved these layers with natural and human-triggered avalanches reported.

Below these layers, the remaining snowpack is generally well settled.

Weather Summary

Wednesday Night
Partly cloudy. 3 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -10 °C.

Thursday
Mix of sun and clouds. 2 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -12 °C.

Friday
Mix of sun and clouds. 1 to 3 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -12 °C.

Saturday
Mostly sunny. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -13 °C.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
  • Watch for areas of hard wind slab on alpine features.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
