In sintesi

New snow and wind has built fresh windslabs, be cautious as you transition in to open terrain.

Keep the persistent slab problem on your mind at treeline and below - be especially cautious if you are exploring areas that don't see regular traffic.

Problemi valanghivi

  • Wind Slabs

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

    Moderate southerly winds have loaded lee features near ridgetop. Be careful as you transition into wind-affected terrain. Wind slabs may be most reactive in areas where they sit over a crust.

  • Persistent Slabs

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

    A layer of surface hoar (up to 40mm below treeline) is buried 50-80cm deep and sits on a crust.

    Use caution in terrain that has not seen recent rider traffic and areas that are more off the beaten path - this is where triggering is most likely.

  • Loose Dry

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

    Watch for loose snow avalanches and fast moving sluff in steep terrain.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.
  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

On Saturday new snow and wind triggered a natural avalanche cycle. A field team observed a size 2.5 from the Frequent flyer path, which stepped down to the Jan 26th layer on the fan, as well as several size 2s from the N side of Cheops. There were also several size 1.5-2s in the steep terrain of the highway corridor.

On Friday, a team remotely triggered 2 size 1.5s between 1600-1850m, on the Jan 26th layer. This was in infrequently travelled terrain below the Avalanche Glacier.

Snowpack Summary

A sneaky 20-30cm of new snow fell Saturday, bringing this weeks totals up to 50-60cm.

Gusty alpine winds continue to build fresh windslabs in exposed terrain.

There are several crusts in the upper snowpack from the springlike temps and sunshine we've had in the past 2 weeks.

The Jan 26th layer of surface hoar, facets, and a crust, is buried down 45-80cm. The largest surface hoar is preserved in sheltered areas below treeline.

Below this the snowpack is well settled/strong.

Weather Summary

A week ridge brings clearing skies and valley fog.

Tonight: Clear periods. Alpine low -10°C. Light West ridgetop winds.

Sun: Sunny periods. High -10 °C. Freezing level (FZL) valley bottom. Light SW wind.

Mon: Isolated flurries. Low -11 °C, High -7 °C. Gusty moderate SW wind.

Tue: Flurries (3-5cm). Low -17 °C, High -9 °C. Light variable wind.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
