Points saillants

Choose simple terrain, free from overhead hazard.

Temperatures are expected to increase, which may cause very large, persistent slab avalanches.

Problèmes avalancheux

  • Wind Slabs

    Wind loaded areas are likely to be rider-triggered. Sheltered terrain will have the best and safest riding.

  • Persistent Slabs

    Persistent slabs will be more likely the warmer it gets. It's a good time to be very conservative in your terrain selection.

  • Loose Wet

    Wet loose avalanches should become more likely with rising temperatures and possible sunshine.

Moderate

Avalanche Summary

Large natural avalanches continue to be reported daily, and are expected to continue with high temperatures and sun.

Large wind slabs and persistent slabs, size 2 to 3, were reported on Monday. As well as a few small, wet loose avalanches.

Snowpack Summary

Up to 30 cm of recent snow is expected to become moist as temperatures rise, and the sun comes out. There is a significant concern for small avalanches to step down to deeper persistent weak layers. These consist of surface hoar, facets, or a crust:

  • The early March layer down 50–100 cm. This is the primary weak layer of concern.

  • Mid-Feb & Late-Jan layers down 80–180 cm. These layers are possible to trigger during warm temperatures, or with a large trigger like a cornice fall or avalanche.

Weather Summary

Tuesday Night

Cloudy with 5 to 10 cm of snow. 15 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1700 m.

Wednesday

Cloudy with 0 to 2 mm/cm of rain/snow. 10 km/h southeast ridgetop wind. Treeline temperature 1 °C. Freezing level 2400 to 2700 m.

Thursday

Cloudy with 15 to 30 cm of snow or rain. 25 to 30 km/h southeast ridgetop wind. Treeline temperature -2 °C. Freezing level falling to 1500 m.

Friday

A mix of sun and cloud, clearing. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1700 m.

Terrain and Travel Advice

  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
  • Avoid travelling on slopes below cornices.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Very large and destructive avalanches could reach valley bottom.
