    Previous strong winds on Monday destroyed the soft snow down into treeline, and created windspread windloading. Be on the lookout for loaded pockets of wind slab, especially in the alpine, where they are more prevalent.

Moderate

Avalanche Summary

No new avalanches were reported on Wednesday. On Tuesday wind slabs up to size 2 were being triggered with explosives at the ski hills.

Snowpack Summary

The previously soft surface snow has been erased with wind in alpine areas, creating windslabs. Some of this wind effect is down into the treeline, but mostly 20-40 cm of soft snow still remains at TL and below. Below ~2300 m, a rain crust exists below the storm snow. The mid- and lower-snowpack is well settled where thicker, and facetting where thin. Tree-line snow depths range from 60-100cm

Weather Summary

West winds will pick up to 40-50 km/h on Thursday, with the potential for a trace of snow, and treeline temperatures steady at -6C.

Friday will be slightly cooler, with diminishing winds.
