Avalanche Activity

LO for 3/2. Existing snowpack well bonded and stable. Localised generally shallow windslab NE and E aspects above 950m. Moderate Haz

Forecast Snow Stability: The existing snowpack will begin to refreeze and be well bonded and stable throughout. Localised accumulations of fresh unstable windslab will develop very gradually through the day mostly on steep North-East and East aspects, above 950 metres. Accumulations will generally be shallow and affect wind sheltered areas such as gullies and coire rims. The avalanche hazard will be Moderate.

Snowpack Structure

Forecast Weather Influences: Becoming colder as the freezing level falls from above the summits to around 800 metres during the night. Showers from very early morning will be snow above 800 metres during daylight hours. Very strong West-South-Westerly winds. Observed Weather Influences: A wet mild day with gale force South-Westerly winds. The freezing level was well above the summits. ObservedSnowStability: After a period of instability overnight, the snowpack is thawing and consolidating. Greatest instability remains on North to East aspects above 1000 metres, mainly in gullies and around coire rims. Elsewhere snowpack stability is generally good. Cornices are prone to collapse. The avalanche hazard is Moderate.
