NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SUN 8/1/06 It has been a cold dry day with moderate South-Easterly winds. Light drifting has lead to further build-up of firm wind slab on North-West to Northerly aspects above 1100 metres, especially around corrie rims and gully heads. On a North aspect at 1140 metres tests showed some instability within the snowpack. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK MON 9/1/06 Dry conditions in the morning will deteriorate by early afternoon as snow moves in from the South on increasingly strong winds. Accumulations of unstable new windslab will form on North-West to North-East aspects above 700 metres, especially on steep lee slopes. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Plateau looking white, soft snow on lee slopes, hard and icy with rimed rocks elsewhere. ICING: Buttresses covered in rime, things well frozen. COMMENT: Make the most of the morning! Conditions due to deteriorate rapidly by the afternoon LOCHABER AVALANCHE HAZARD 1500 HRS SUN 8/1/06 Today has been cold and dry with light Southerly winds. There have been no new deposits of snow. The snowpack remains stable and well-bonded. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 9/1/06 Dry and cold conditions are expected overnight and into Monday morning, then a strengthening Southerly wind will bring some snow. Deposits of windslab will accumulate on North aspects and in sheltered gullies. Some instability will be present between the new slab and the old re-frozen snowpack. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 900m on mainly N to E aspects, more expected by mid-day. ICING: Some ice climbing possible. Light rime ice present on high crags. COMMENT: Freezing level rising to 800m by mid-day. GLENCOE AVALANCHE HAZARD 1500 HRS SUN 8/1/06 Cold, dry and settled conditions have left the snowpack in a well bonded condition. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 9/1/06 Cold and dry conditions will give way to Southerly gales and new snow on Monday afternoon. Stability will be good for much of the period but accumulations of windslab will form in sheltered areas such as summit gullies as the stormy conditions affect the area. These accumulations will be unstable where they form on steeper slopes and where old snow underlies. The avalanche hazard will become Considerable (Category 3) CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 900 metres. ICING: Freezing level 450 metres overnight rising to 800 metres on Monday. COMMENT: Severe gales over the tops on Monday. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SUN 8/1/06 There is almost full winter cover above 900 metres now due to a trace of fresh snow and heavy rime ice. Conditions underfoot are variable with breakable crust, water ice and firm snow-ice all being encountered. New deposits are minimal and the snow remains well bonded. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 9/1/06 Conditions will remain unchanged overnight and during the morning. Snow arriving in the afternoon on strong winds will rapidly form unstable deposits in sheltered locations on NW to NE aspects above 700 metres. As depth is acquired on steeper terrain bonding will be poor especially where a snow-ice base is present. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Thin but full cover above 900 metres. Broken cover down to 600 metres. ICING: Some limited ice on the crags with rocks rimed. COMMENT: Conditions deteriorating after mid-day. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS SUN 8/1/06 Sunday was cold, dry and bright with very light Southerly winds. The snowpack consists of patches of well-stabilised, re- frozen snow-ice. The largest ones are confined to North through to South-East facing gully tops and corrie rims above 900 metres. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 9/1/06 It will remain cold and dry overnight but winds will strengthen from the South and carry snow showers that will affect the area later on Monday. Stability will be good in all locations until new snow accumulations begin to form on steep North to East aspects above 900 metres. The avalanche hazard will rise to Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Poor. Isolated patches above 800m though likely to improve for a time with onset of snow showers. ICING: Sustained cold conditions have helped improve principal ice routes but overall build up still relatively modest. COMMENT: Strong winds forecast for later on Monday. -------------------------------------------------------------------------------
