TO for 31.12. Fresh areas of moderately bonded windslab on S through W to N aspects above 700m. Some cross loading. Hazard Moderate.

TO for 31.12. Fresh areas of moderately bonded windslab on S through W to N aspects above 700m. Some cross loading. Hazard Moderate.

Forecast Snow Stability: The snowpack will firm up as the freezing level lowers. Fresh isolated pockets of windslab will develop on several aspects as the wind changes direction. These moderately bonded instabilities will mainly be present on South through West to North aspects above 700 metres. Areas most affected will be steep wind sheltered terrain such as coire rims, gullies and ridge crest. There will be some cross loading and cornice growth is likely. The avalanche hazard will be Moderate.

Forecast Weather Influences: The gale force North-West winds will lower in strength at first becoming moderate South-Westerly overnight then moving around the compass to become North-Easterly by the end of the period. Moderate amounts of snow showers are expected. Overnight, the freezing level will lower abruptly from 800 metres to hover around 450 metres, then lower gradually to around 200 metres. Observed Weather Influences: Strong to gale South-South-West winds with heavy persistent rain showers in the glen. Visibility has been poor with showers of sleet and snow from around 500 metres and above. ObservedSnowStability: The snow has been stripped at lower levels. Areas of moderately bonded windslab has developed on steeper wind sheltered terrain mainly on West through North to North-East aspects above 700 metres. These instabilities are affecting coire rims, gullies and ridge flanks. The avalanche hazard is Moderate.
