    New wind slabs are developing due to strong Southwest winds and new snow. Some recent wind slabs on Easterly aspects may be stripped or reverse loaded by the new storm.

Snowpack Summary

Strong Southwest winds are re-distributing new snow into wind slabs, and reverse loading areas that were stripped by recent Northwest winds. These wind slabs may be sitting above recently developed surface hoar and surface facets in area where they were not stripped by the wind. Strong solar radiation may have developed sun crusts on solar aspects up to about 2000 metres. The mid pack is reported to be well settled without any layers of concern. Depth hoar and facets are reported near the ground in areas with a thin snow pack.
