10-30 cm of storm snow has fallen on a melt freeze crust that formed over the holidays. Above 1500 m this snow may remain dry and available for transport by the strong southerly winds forming wind slabs. Where the temperature has warmed above 0 °C, this snow will be moist to wet and settling rapidly. Beneath this there is moist snow to ground. Below treeline, you'll find dirt, or shallow and wet snow.
The current snow depth ranges from 70 to 120 cm at treeline, diminishing rapidly below 1000 m.
