Wind slabs may be reactive to human triggering at upper elevations.

On Saturday, there were a few reports of natural and human triggered wind slab avalanches, mainly in the alpine on north and east facing slopes.On Thursday, there were a few reports of natural and human triggered storm and wind slab avalanches in the alpine, as well as a few human triggered loose wet avalanches.

10-20 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. Recent snowfall amounts taper quickly below treeline.The base of the snowpack is composed of sugary faceted snow. The likelihood of triggering an avalanche on this layer is lower during colder periods and elevated during intense warming.Snow is disappearing rapidly at lower elevations.
