In sintesi

Wind slab formation has been extensive and could extend into openings below treeline.

Persistent slabs sitting on a weak layer of surface hoar may be possible to human trigger.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–3

    Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2.5

    Be aware of the potential for remote triggering and large avalanches due to buried surface hoar, especially at treeline and below.

Confidence

Moderate

  • Persistent slabs could become more likely with the forecast weather.

Avalanche Summary

On Tuesday, an explosive triggered size 2 wind slab was reported on a northeast aspect in the alpine.

Observations are currently very limited in this region. Please consider sharing your observations with the Mountain Information Network.

Snowpack Summary

Up to 15 cm of recent snow accompanied by strong to extreme southwest wind has formed deeper deposits on north and east aspects. In sheltered terrain it could overlie a layer of surface hoar or a sun crust. The snow surface may become moist on sun exposed slopes.

Several weak layers comprised of facets, surface hoar, or crusts could exist in the top 20 to 60 cm of the snowpack.

The mid and lower snowpack are well settled.

Terrain and Travel Advice

  • Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • In times of uncertainty, conservative terrain choices are our best defense.
