Forecast Snow Stability: Poorly bonded windslab will become deeper and more extensive on all steep South-West through West to Northerly aspects mostly above 850m but also more localised accumulations above 700m in wind sheltered places. Coire rims, headwalls and gully tops especially affected. Weak cornices will continue to build over all same aspects. Good stability on all ridges and wind exposed NE to SE aspects where firm or crusty snow ice is widespread above 700m. The avalanche hazard will be Considerable
Forecast Weather Influences: Winds continuing East-South-Easterly will be Gale to Storm force in strength from mid morning. Precipitation will fall as light snow overnight becoming persistent and heavy from early morning and for the rest of the forecast period. Snow lying above 400m or so. Observed Weather Influences: A cold day with strong East-South-Easterly winds persisting. Light snow showers but a mostly dry day, drifting at higher elevations. Freezing level around 750m. ObservedSnowStability: The old snow lying on all aspects is stable breakable crust or firm and icy. Wind exposed NE to SE aspects are especially scoured and firm. New accumulations of localised poorly bonded windslab is present in wind sheltered places above 850 metres on mainly South-Westerly through West to North-Westerly aspects. Coire rims, headwalls, gully tops especially affected. Cornices building on same aspects. The avalanche hazard is Moderate
