NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 15/2/05 A sunny day with light North-Westerly winds has drifted lying snow on to mainly Easterly aspects above 800 metres. The snowpack has become generally stable except for weaknesses that remain at depth in the snow on mainly Southerly aspects and in some isolated accumulations on North-Easterly aspects above 800 metres where field tests produced easy releases.The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK WED 16/2/05 Moderate South-Westerly winds with some rain and a freezing level above the summits will moisten the snow pack on all aspects and at all altitudes. The snowpack will be unstable on mainly Southerly and Easterly aspects above 800 metres. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Good compact snow for travelling on foot and ski can be found on the plateau. ICING: Good climbing in the Northern Corries COMMENT: Warm weather ahead but may return to colder conditions in a few days !! LOCHABER AVALANCHE HAZARD 1500 HRS TUE 15/2/05 Areas of weakly bonded windslab still exist in many areas above 1000m. These areas are most common at the tops of East, South-East and South facing scarp slopes and gullies. In these areas the avalanche hazard is Considerable ( Category 3 ). Wind scoured slopes remain stable. AVALANCHE HAZARD OUTLOOK WED 16/2/05 A weak warm front will bring rain to all levels overnight and during Wednesday. Rainfall is not expected to be heavy, but may be sufficient to overload steep, weakly bonded slopes with an East, South-East and South aspect above 1000m. The avalanche hazard will be Considerable ( Category 3 ). Some cornices will become unstable and prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Good snow cover in East facing corries and generally down to 500m. ICING: Ice slowly starting to form on some routes. COMMENT: Colder weather expected to return by Thursday. GLENCOE AVALANCHE HAZARD 1500 HRS TUE 15/2/05 Stability continues to improve in most locations with the dry and settled conditions affecting the area. Many slopes exposed to the recent strong Northerly winds are scoured. Areas of windslab exist in sheltered gullies and on mainly East to Southerly aspects above 850 metres. Where deeper accumulations of windslab lie on steep slopes or where strong solar warming is occuring bonding remains suspect. The avalanche hazard is Moderate (Category 2) AVALANCHE HAZARD OUTLOOK WED 16/2/05 A weak warm front will give milder conditions with moderate rain at all levels overnight and through Wednesday. Instabilities will form on steep slopes as the snowpack becomes increasingly wet. Areas of greatest instability will be all sheltered gullies and slopes with a North-East through to Southerly aspect mainly above 850 metres, where avalanches and cornice collapse are likely. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 500 metres on Tuesday. ICING: Freezing level expected to be around 1700 metres through the period. COMMENT: All the classic routes in the glen receiving ascents on Tuesday complete with superb weather, outlook mild and wet for Wednesday. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 15/2/05 It has been a stunning day, providing better observation conditions. Some consolidation has taken place but yesterday's drifted deposits contain graupel layers and are demonstrating poor stability. These moderately to weakly bonded deposits are present in very sheltered locations on E through S to SW aspects above 650 metres. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK WED 16/2/05 The freezing level will rise to above the summits. The moderately to weakly bonded deposits that are present in very sheltered locations on E through S to SW aspects above 650 metres will be de-stabilised by the rising temperatures. Avalanches are likely in steeper locations such as gully exits and scarp slopes. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: A combination of icy wind scoured slopes and deep drifts. ICING: 1500 metre freezing level on Wednesday. COMMENT: Ski touring available for the keen. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS TUE 15/2/05 Strong sunshine and light variable winds have prevailed. The snowpack shows some signs of consolidation, but cold temperatures are maintaining weak sub-surface layers in deeper deposits. Moderate to easy shears were obtained in areas tested. Weakly bonded windslab is present on North-East through East to South aspects above 800 metres. The avalanche hazard is Considerable (Category 3). Very large unstable cornices are present above many steep aspects. AVALANCHE HAZARD OUTLOOK WED 16/2/05 Strong South-West winds will bring freezing levels rising to above the summits. Rain and mild temperatures will add further loading to existing weakly bonded windslab with a period of high instability ensuing. Weakly bonded windslab is present on North-East through East to South aspects above 800 metres and here avalanches will occur. The avalanche hazard will be High (Category 4). Large cornices will also be prone to collapse and run outs will be long. CLIMBING CONDITIONS SNOW DISTRIBUTION: Good cover at all levels. Fantastic ski-touring conditions; skis recommended for travel unless you like swimming up hill! ICING: Mostly buried with exits from most gullies holding weak slab or overhung by monster cornices. COMMENT: Careful route choice advised in wet conditions on Wednesday with debris run outs expected to be long! -------------------------------------------------------------------------------
