On Monday, several natural and human triggered storm slab avalanches up to size 2.5 were reported on west, north and east aspects in the alpine. A few natural and human triggered wind slabs to size 1.5 were reported from immediate lee features in the alpine. Several natural loose avalanches up to size 2.5 were observed on northerly aspects at treeline and in the alpine.On Sunday and Saturday, there were a few reports of natural and human triggered storm/wind slab avalanches up to size 2 at treeline and alpine elevations. There were also reports of several natural and human triggered loose wet avalanches up to size 1.5 on steep solar slopes and below treeline.
15 to 40 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. These slopes may also have a layer of sugary faceted snow buried 60 to 80 cm. On northern aspects the new snow is not bonding as well and humans can trigger storm slab avalanches. Strong southwest winds on Monday created isolated wind slabs in lee features at treeline and in the alpine. On sun exposed slopes the new snow might release as loose wet avalanches. Recent snowfall amounts taper quickly below treeline. Snow is disappearing rapidly at lower elevations.
