    This layer is now bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.

Weather Forecast

Remaining cold with the odd isolated flurry of snow.

Snowpack Summary

Previous wind slabs are providing bridging strength over a weak basal facet layer at treeline and alpine elevations. Extensive scouring of the snowpack has occurred in the high alpine. Last nights snow is giving dust on crust conditions and soft slabs in sheltered locations.

Avalanche Summary

Field teams observed three size 2 slab avalanches that occurred in the last 12 hours on southerly aspects at treeline. These had been triggered by last nights snow and strong northerly winds redistributing snow onto the existing surface hoar/facet layer.

Confidence

Due to the number of field observations on Thursday
