Snowpack Summary
A MIN report from Shames on Thursday describes 8-12 cm soft wind slabs at 1300 metres on southerly aspects that were not well bonded to the underlying crust. The distribution of surface hoar left after the recent clear weather is our biggest knowledge gap. New storm slabs are widespread and variable in depth. The north of the region has more snow than the south and the temperatures in the north have been cooler with lower freezing levels.
