Forecast Snow Stability: Fresh poorly bonded windslab will be deposited from the start of the day, mostly on South-West though West to North-West aspects above 850 metres. Steep wind sheltered locations, such as coire rims, convexities and gully tops will be affected. Slopes exposed to wind will be scoured, while at lower elevations snow patches will remain moist and stable. Cornices will build from early in the day. The avalanche hazard will be Moderate.

Winds were fresh and from the East. ObservedSnowStability: The snowpack is moist and consolidated in most locations, with a widespread soft crust.
