NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 13/3/06 Very strong South-Westerly winds with snow have continued to affect the area. Drifted accumulations of windslab are forming on North to North-Easterly aspects above 600 metres. Instabilites are present in the snowpack and releases occurred during slope tests. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK TUE 14/3/06 Overnight, very strong South-South-Easterly winds with heavy snow will continue to cause severe drifting and accumulations of unstable windslab snow will form mainly on North-Westerly to North- Easterly aspects above 500 metres where avalanches will occur. The avalanche hazard will be High(Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Whiteout and severe drifting. ICING: Some refreezing of snowpack above 500m. COMMENT: Continuing snowfall and high winds. LOCHABER AVALANCHE HAZARD 1500 HRS MON 13/3/06 A brief thaw during last night has been followed by cooler conditions pushing in to the area during this morning. Snow showers have affected the area with strong Southerly winds. Areas of unstable snow are present, mainly on steep North- West, North and North-East aspects above 1000m. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 14/3/06 Heavy snow above 600m overnight will give way to snow showers during Tuesday. This will be accompanied by strong South to South-East winds. Large areas of unstable windslab will form overnight and during Tuesday. Greatest accumulations will be on steep North-West, North and North-East aspects above 900m. Avalanches will occur in these locations. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Fresh snow falling above 600m. ICING: Freezing level lowering to 500m overnight and during Tuesday. COMMENT: Strong SSE winds expected. GLENCOE AVALANCHE HAZARD 1500 HRS MON 13/3/06 New snow above 500 metres accompanied by strong Southerly winds has affected the area. More weakly bonded deposits of layered windslab have formed in many sheltered locations. The greatest accumulations of unstable snow are above 800m on North-West to North-East aspects but especially around the tops of all sheltered gullies and on scarp slopes. The avalanche hazard is High (Category 4). Cornices are fragile. AVALANCHE HAZARD OUTLOOK TUE 14/3/06 Heavy snow showers will continue through Monday night and Tuesday morning with very strong South-South-East winds. This will form further accumulations of windslab in sheltered areas. Bonding will be poor on steep slopes, gullies and scarp slopes of all aspects but mainly those with a West through North to North-Easterly aspect above 800 metres. Avalanches will occur in these areas due to weakly bonded snow the avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Main cover above 500 metres. ICING: Freezing level 500 metres. COMMENT: Ridges and buttresses are the safer option. Deep accumulations of new snow will require care on approaches and descents. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 13/3/06 Snow showers were light but strong winds continued to re-distribute deposits. Some consolidation of recent windslab has occurred but stability remains poor. Deeper areas are to be found on W through N to NE aspects above 500 metres. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 14/3/06 Overnight there will be substantial snowfall and very strong winds that will ease gradually during the day. Deep weakly bonded windslab will be found in sheltered locations above 500 metres mainly on W through N to NE aspects where avalanches will occur. Stability of newly formed cornices will be poor. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Deep drifts with exposed areas scoured. ICING: Any significant ice is likely to be buried. COMMENT: Paths will require some determined trail breaking. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 13/3/06 A heavy thaw has much depleted snow cover below 400 metres. Above 800 metres snow showers overnight and during the day on strong Southerly winds have resulted in further accumulations of wind-blown snow on North-West to North- East facing aspects. Avalanche debris was noted high on North- West facing slopes of Coire a' Chriochairein above 850 metres. Recent accumulations overlie a soft base layer which when tested failed readily when subjected to loading. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK TUE 14/3/06 A further band of heavy snow overnight on strong South-South- East winds will ease during the day. Windslab will continue to develop on steep sheltered NW to NE aspects above 850 metres where avalanches will occur. The avalanche hazard will remain High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Soft snow above 400 metres with deep drifts in sheltered locations. Thawing snow at valley level. ICING: Not visible at present - buried under fresh snow. COMMENT: Treacherous `man traps' either side of railway sleepers on main path to Coire Ardair (most now detected!) -------------------------------------------------------------------------------
