In sintesi

Conservative terrain choices are the best defense against uncertainty in persistent slabs.

Despite the recent wind, good riding can still be found in sheltered features.

Problemi valanghivi

  • Wind Slabs

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

    Rider triggerable wind slabs could still linger in the alpine. If triggered, wind slabs may step down to deeper layers, causing larger avalanches.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3.5

    A persistent weak layer is buried 1 - 2 m. This is a low-probability, high-consequence problem. Signs of instability may not be obvious. The best defence is smaller, low-consequence terrain.

Snowpack Summary

Previous strong wind has created pressed surfaces and wind slab in exposed terrain. A new sun crust could be on or near the surface.

20 to 40 cm of soft snow from last week remains in wind-sheltered areas. Reports suggest this snow is bonding fairly well to previous surfaces.

A thick crust with facets over it, from late January, can be found down 100 to 200 cm. We do not have concerns about the snowpack below this layer.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

Over the weekend a few dry loose avalanches were observed in steep terrain. A skier accidentally triggered a cornice while trying to create access to a ski line, this resulted in a dry loose avalanche on the slope below.

Field observations have been limited over the last few days. If you are heading to the backcountry, please submit your observations to the Mountain Information Network.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • In times of uncertainty, conservative terrain choices are our best defense.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
