NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 29/12/97 Colder conditions with no further snowfall have resulted in a sparse and generally stable snowpack. Small pockets of windslab still persist on mainly E to SE aspects although even in these locations stability is fairly good. Low (Category 1) hazard of avalanche. AVALANCHE HAZARD OUTLOOK TUE 30/12/97 Moderate to high snow overnight and tomorrow with rain below 1100m on strong S winds will see the development of wind blown snow at the tops of many N facing slopes and gullies. With any significant development over the period a Considerable (Category 3) hazard of avalanche will result in these locations, where avalanches are likely. CLIMBING CONDITIONS SNOW DISTRIBUTION: Very good general cover in plateau areas, poor below 800m. ICING: Many buttresses still plastered with most recent deposits and rime ice. Ice not yet in any great quantities. Many routes being done in Northern Coires. COMMENT: Poor mountain conditions expected for Tuesday with the return of milder/windy weather LOCHABER AVALANCHE HAZARD 1500 HRS MON 29/12/97 Areas of unstable windslab are present, with greatest accumulations being on easterly aspects, notably on scarp slopes and the tops of gullies above 1100m. Unconsolidated soft slab is also present above 900m in many corries. The avalanche hazard is Considerable (Category 3). Cornices are unstable and prone to collapse. AVALANCHE HAZARD OUTLOOK TUE 30/12/97 Rain at all levels and strong southerly winds are expected overnight and during Tuesday. The existing windslab will thaw at all levels producing wet snow avalanches on many aspects. The avalanche hazard will be High (Category 4). As the day progresses, the snowpack will gradually consolidate and stabilise. CLIMBING CONDITIONS SNOW DISTRIBUTION: The existing snowcover will thaw at all levels during Tuesday, leaving a fairly patchy cover. ICING: Freezing level rising above the summits overnight and during Tuesday. COMMENT: Climbing conditions deteriorating on Tuesday. GLENCOE AVALANCHE HAZARD 1500 HRS MON 29/12/97 Heavy showers have deposited snow on most aspects. On slopes facing NW-E there are areas where deeper soft slab exists. Steep summit gullies of N facing corries contain localised areas of unstable soft slab.In these areas the avalanche hazard is Considerable (Category 3) AVALANCHE HAZARD OUTLOOK TUE 30/12/97 Milder conditions and heavy rain to the summits will make the snowpack unstable.Where deeper snow lies on steep ground avalanches will occur. In steep summit gullies of N facing corries the avalanche hazard will be High (Category 4) CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 700m. ICING: Ice on rocks above 400m. COMMENT: Buttresses will become stripped.After a time snow will consolidate and stabilise. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 29/12/97. The sparse snowpack has been scoured in most places leaving it icy. However the cold temperatures have maintained some very localised deposits of poorly bonded snow in sheltered gully areas above 950m. The avalanche hazard is Moderate (Category 2) where accumulations are greatest. AVALANCHE HAZARD OUTLOOK TUE 30/12/97. Strong S winds and moderate amounts of snow overnight will lead to windslab build up mainly on N facing slopes and gullies above 950m. During Tuesday, a return to mild conditions with rain, will saturate the new snow leaving it weakly bonded to existing snow ice. The avalanche hazard will become Considerable (Category 3) where accumulations are greatest. CLIMBING CONDITIONS SNOW DISTRIBUTION: The snowpack remains sparse, but some limited ski touring is possible above 950m. ICING: Lean ice conditions in most areas, with buttresses rimed up and turf mostly frozen. COMMENT: Thaw conditions expected at all levels on Tuesday. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 29/12/97 Cold,calm and clear conditions have led to little change in the snowpack. Large areas of weakly bonded windslab still exist, primarily on NW to SSE facing slopes above 950m. Where this windslab exists the avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 30/12/97 Heavy snow on a strong Southerly wind overnight and tomorrow will lead to further accumulations of weakly bonded windslab. This will primarily be on slopes with a NW to NE aspect, above 1000m, where avalanches are likely. At lower altitudes some consolidation will occur. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow level is 600m, but will rise tomorrow. Good cover on the plateau. ICING: Still very thin but should start to improve now. COMMENT: An excellent day on the hill for all those who graced us with their presence. -------------------------------------------------------------------------------
