Avalanche Summary

No new reports of avalanches since Friday when natural and remote rider triggered wind slabs size 1.5-2 were observed on north aspects in the alpine. Wind slabs appeared to be less sensitive on Saturday according to this MIN report.

Snowpack Summary

Around 20 cm of recent snow has been redistributed by wind in most areas. Good snow quality can be found in wind-sheltered terrain. In these areas, the new snow may sit over a layer of surface hoar.

Below 1500 m, a thick melt-freeze crust is buried 50 - 100 cm deep.
