10-20 cm of recent new snow and winds switching direction are promoting fresh wind slab development over previously wind affected surfaces and in some places weak facetted snow.
Temperatures and freezing levels will continue to slowly warm and rise, expect this to increase the sensitivity of wind slabs to human triggering.
10-20 cm of recent new snow and winds switching direction are promoting fresh wind slab development over previously wind affected surfaces and in some places weak facetted snow.
On Friday, both natural and explosive controlled large (size 2) wind slab avalanches have been reported at elevations above 2200 m and on north aspect terrain. On Thursday extensive explosive control at a number of professional operations, produced large both wind and storm slab avalanches up to size (2.5).
10-25 cm of recent new snow has covered weak, faceted snow in many areas and wind-affected surfaces in open areas at all elevations.
A layer of surface hoar is found down 70 cm in sheltered, north-facing terrain. This layer appears as a sun crust on south-facing slopes. As temperatures slowly warm expect this layer to become reactive to human triggering.
A thick crust deep in the snowpack largely protects any weak layers further down in the snowpack from being triggered.
