Points saillants

Wind-loaded areas hold the most snow but they also have the highest avalanche risk at this time.

    Watch for patches of soft wind slab in exposed lees. Investigate the bond between wind slabs and underlying surfaces before committing.

Avalanche Summary

No recent avalanches have been reported in the region. Thanks to all those who have submitted a MIN report already this year, all the information is really helpful for forecasters.

Snowpack Summary

15 to 30 cm of unconsolidated snow overlies a series of crusts and in exposed areas old wind slab.

At treeline, the height of snow ranges from approximately 50 to 90 cm. At 1500 m snow depths decrease significantly.

The snowpack at all elevations is very shallow and contains many potential hazards just beneath the snow surface.

Data is very limited at this time. If you are recreating in the mountains please consider submitting a MIN report.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
  • Be carefull around freshly wind loaded features.
