NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 16/1/01 The weather continues tp be cold and clear, with a significant easing in the Southerly wind. The weak layer continues to be present and an avalanche incident was noted on a NNE aspect at 1000 metres in Coire an t-Sneachda. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK WED 17/1/01 Wind transport of snow will ease somewhat and the cool clear weather is forecast to continue. The weak layer of buried surface hoar and facets will still be present. There will be significant slab load from Southerly wind on West, North and East aspects above 850 metres, where avalanches are likely. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Little change on the plateau, some skiable slopes are loaded with wind slab. ICING: Very little change. COMMENT: Nineteen (19) people have been reported in avalanches this winter. So far no injuries. Special care required. LOCHABER AVALANCHE HAZARD 1500 HRS TUE 16/1/01 Areas of hard slab are present, mainly on steep N, NE and E facing slopes and gullies above 1000m. Southerly winds overnight have formed fresh slab on sheltered NW, N and NE aspects. Wind blown slopes are generally hard frozen and stable. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 17/1/01 Cold and dry conditions, with a SE airflow will continue for the forecast period. Isolated areas of hard slab will remain, mainly on steep NW through to NE and E aspects above 1000m. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Main accumulations remain above 800m. ICING: Remaining cold at all levels. COMMENT: Large areas of water ice and old frozen snow present on many paths, even at lower altitudes GLENCOE AVALANCHE HAZARD 1500 HRS TUE 16/1/01 Fresh SE winds have re-distributed snow onto more northerly aspects. NW to NE facing corrie headwalls and sheltered summit gullies contain pockets of dense windslab which is potentially unstable. The snowpack elsewhere above 750m is generally stable with a firm crust. Slopes exposed to the wind are icy. Avalanche hazard Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 17/1/01 The cold conditions will continue with little change to the snowpack. Pockets of dense layered windslab will exist in sheltered summit gullies and NW to NE corrie headwalls. Instabilities will remain within these layers particularly in steep locations. The avalanche hazard will be Moderate (Category 2). Elsewhere the snowpack will have a firm crust which will be icy on exposed slopes. CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow cover above 750m. ICING: Ice on rocks and paths above 200m. COMMENT: Routes such as NW Gully, Arch Gully and Deep Cut Chimney receiving ascents. Crampons and axe essential on icy corrie paths,headwalls and summit slopes. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 16/1/01 The snow pack is generally well bonded but there is some surface instability on most aspects due to facet development. Deeper areas of windslab exist in sheltered locations on NW to NE aspects above 900 metres. Greatest hazard is to be found in gully exits where recent cornice development remains unstable. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 17/1/01 There will be little change to the current situation with areas of windslab existing in sheltered locations on NW to NE aspects above 900 metres. Within the snowpack facet development will continue producing widespread surface instability. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Good cover above 900 metres. ICING: Continuing lean and variable. COMMENT: High plateau areas giving enjoyable ski touring conditions. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS TUE 16/1/01 A light South East wind, cold temperatures and clear mountain conditions have had little change to present snowpack distribution. However isolated areas of highly unstable windslab still persist on North West through North East to South East aspects above 800 metres. Hard windslab is still covering a layer of depth hoar which is providing an efficient sliding surface. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK WED 17/1/01 Cold and clear with a light South East wind will have little change to present snowpack conditions. Isolated areas of highly unstable windslab will remain on North West through North East to South East aspects above 800 metres. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Main cover above 750 metres, good cover on plateau. ICING: Good on certain Post Face and Inner Coire routes. Certain routes have had a thrashing though! COMMENT: Weather remaining awesome!! -------------------------------------------------------------------------------
