On Friday, there were reports of a few natural and human triggered storm and wind slab avalanches up to size 2. These were mainly on north to east aspects in the alpine.On Thursday, there were several reports of natural and human triggered storm slab avalanches up to size 1.5, as well as a few natural loose wet avalanches up to size 1.5.On Tuesday, there were two reports of glide slab avalanches, size 1 and 2.5. These occurred on southeast aspects between 2200-2400 m. Both released on rock slabs.

10-30 cm of recent storm snow sits on a melt-freeze crust on all aspects except for north slopes above 2000 m, where it sits on dry snow and surface hoar (feathery crystals) in some areas. Recent snowfall amounts taper quickly below treeline.North facing slopes above 2000 m may also have a layer of sugary faceted snow buried 50 to 70 cm.Snow is disappearing rapidly at lower elevations.
