NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 8/1/01 There has been light snow above 750 metres and North West winds about 30 mph. The new slab, building now over the past 48 hours shears cleanly in field tests; however it does not show any propagation. Due to the cold mid-pack temperatures there has been little change in any buried surface hoar or facets that still exist. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 9/1/01 Very light snow showers and light variable winds are forecast for the period. On small terrain features the slab will be well bridged, the stability will be fair. On some larger convex slopes above 850 metres of NE to SE aspect there will be isolated areas where the deeper instability persists. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Slowly increasing above 800 metres. ICING: Marginally acceptable if your expectations are not high. COMMENT: Nearly possible to combine a ski tour with a climb. LOCHABER AVALANCHE HAZARD 1500 HRS MON 8/1/01 Fresh snow overnight has produced areas of windslab which is poorly bonded to the underlying snow layers. Greatest accumulations are on steep slopes and gullies with a N, NE and E aspect above 1000m. The avalanche hazard is Considerable (Category 3). Small unstable cornices are also building above these aspects. AVALANCHE HAZARD OUTLOOK TUE 9/1/01 Cold temperatures and light snow showers will have little effect on the existing snowpack. Areas of unstable snow will still be present, mainly on steep N, NE and E facing slopes and gullies above 1000m. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Main accumulations remain above 800m. ICING: Freezing at all levels on Tuesday. COMMENT: Colder conditions should improve climbing. GLENCOE AVALANCHE HAZARD 1500 HRS MON 8/1/01 A thin melt-freeze crust exists on the surface of much of the snowpack. On North to South-East facing corrie headwalls and in summit gullies deep soft slab exists beneath the crust. New snow and windblown snow have formed areas of potentially unstable windslab on slopes with an East to South aspect and in sheltered gullies mainly above 900m. Avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 9/1/01 Colder conditions with an overnight frost at all levels will further stabilise the snowpack. Light winds and a trace of new snow will have little effect on the general condition of the snowpack. Deeper accumulations of existing soft slab mainly to be found in sheltered gullies and on slopes with a North to South-East aspect will become moderately well bonded. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow cover above 750m. ICING: Ice on rocks above 850m. COMMENT: Colder conditions returning, climbing conditions improving. Higher buttress routes are receiving ascents. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 8/1/01 New snowfall was light and has not added much to existing snow. Consolidation is largely good with only a few areas of moderate stability remaining, mainly on steep slopes above 950 metres on N aspects. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 9/1/01 New deposits of snow will not achieve any reasonable depth. A drop in the freezing level will continue to strengthen the snowpack. The majority of snow will be firm and well bonded with greatest hazard to be found on steeper slopes above 950 metres, mainly on N aspects. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy up to 900m reasonable thereafter. ICING: What is around is variable in quality. COMMENT: Ski touring is possible in higher plateau areas. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 8/1/01 A fresh North West wind has accumulated shallow moderately bonded windslab on East to South aspects above 850 metres. Moderately bonded hard slab persists on North West to East aspects above 850 metres. The avalanche hazard is Moderate (Category 2). As the freezing level was just below the summits fresh cornices remain unstable, debris was noted from cornice collapse below the Sash and the Pumpkin. AVALANCHE HAZARD OUTLOOK TUE 9/1/01 Light snowfall on a light South East wind will add to moderately bonded windslab deposits on North West to North East aspects above 850 metres. The avalanche hazard will remain Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Main cover above 800 metres. ICING: Post face and Inner Coire provide the best entertainment. COMMENT:Ice thawing slightly, should improve with Tuesday's colder temperatures. -------------------------------------------------------------------------------
