Avalanche Summary
On Friday numerous natural loose wet avalanches to size 2 were reported on steep solar aspects in the alpine.
Snowpack Summary
Sunday's snow will bury the widespread surface hoar being reported up to 20mm in size on shady aspects at all elevations throughout the region. The strong winds associated with Sunday's storm will build fresh wind slabs on lee features in alpine. Cornices are large and looming. The mid February layer is down 70-100cm and is the primary layer of concern. This layer is a crust and generally well bonded to the overlying persistent slab. However, in isolated areas on northerly aspects between 1800-2100m the layer is surface hoar which means there are still a few "land mines" out there that if triggered could produce large destructive avalanches.
