04.12 LO Windslab problem above 1050m on NW through N to NE aspects. Avalanche hazard is moderate.

Forecast Snow Stability: Fresh deposits of moderately bonded windslab will continue to accumulate on North-West through North to East facing aspects above 1050 meters. These instabilities are expected to be localised affecting wind sheltered locations such as gully tops and corrie headwalls. On other aspects and at lower elevations, the snowpack is generally stable. The avalanche hazard will be Moderate.
