Avalanche Summary
A natural and skier-triggered avalanche cycle with slabs up to size 2 was observed over the last couple of days. These were failing on the mid-December surface hoar on north through east aspects from 1700m to the peaks. Wind loading from the south-west overnight Sunday led to naturally-triggered wind-slabs on lee slopes on Monday morning. Touchy conditions are likely to continue through the forecast period.
Snowpack Summary
Up to 20cm of new snow has been redistributed by south-west winds into touchy wind-slabs on lee slopes. A buried surface hoar layer from mid-December around 30cm down is now highly reactive. It is well-preserved with 10-15mm crystals and is most reactive well below ridges in protected terrain. The mid-pack is generally well settled. Facets exist at the base of the snowpack.
