Windy with some snowpack instability

Snowpack cracking underfoot on layer of facets NE aspect 1000m
At the snowprofile site
Unstable layers of facetted crystals remain below the windslab and above the old hard snow pack this has been developing in the cold temperatures and strong temperature gradients - go here for info on this

This has produced isolated areas of weak snow with steep N to E aspects and convex terrain above 900m being most affected.
