Snowpack Summary

Around 10 to 20 cm of recent snow fell with strong southwest winds. This snow fell onto a sun crust on south aspects and feathery surface hoar in sheltered and shaded areas at all elevation bands. The new snow may not bond well to these layers, particularly once the new snow gains slab properties.Below this, the snowpack is generally well-settled.
