NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SUN 13/2/05 There have been frequent snow showers on strong Northerly winds. The new snow has fallen at all levels and with heavy drifting further windslab has formed on sheltered West through North to Southerly aspects above 650 metres. The snowpack is weakly bonded especially on steep slopes where deep accumulations lie. Shooting cracks were observed with a low additional load at 700 metres on a Westerly aspect. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK MON 14/2/05 Snow showers will continue on easing North winds. Avalanches will occur on many steep lee aspects above 650 metres due to weakly bonded windslab. Pockets of windslab will affect sheltered gully heads and crag aprons on Northerly aspects due to localised wind effects. Cornices will continue to develop on Southerly aspects. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow at all levels with deep drifts. ICING: Some visible on steeper crags but mainly buried. COMMENT: Deep drifts causing difficult walking conditions LOCHABER AVALANCHE HAZARD 1500 HRS SUN 13/2/05 Overnight snow showers and strong winds have continued through Sunday morning. Areas of windslab have formed in many sheltered locations, with greatest accumulations on East, South-East and South facing slopes and gullies above 900m. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK MON 14/2/05 The strong Northerly airflow will slowly ease during Monday, with a decrease in snow showers. Unstable windslab will remain in many sheltered locations, with greatest accumulations on East, South-East and South facing slopes and gullies above 900M. Avalanches will occur in these areas. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: New snow down to 500M. ICING: Freezing level around 400M on Monday. COMMENT: Windslab and unstable cornices have formed. GLENCOE AVALANCHE HAZARD 1500 HRS SUN 13/2/05 Variable winds overnight and very strong Northerly gales today have formed deep unstable windslab in many sheltered gullies and on slopes mainly with a North-East through to Southerly aspect above 800 metres. Stability is poor where windslab lies on steep slopes. Avalanche debris was noted below Easterly aspects from 950 metres on Buachaille Etive Mor. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK MON 14/2/05 The cold and strong Northerly airflow will continue overnight, easing through Monday. With snow showers continuing and low temperatures the condition of the snowpack will not significantly alter. Deep unstable windslab will remain in all gullies sheltered from the recent strong winds and on slopes mainly with a North-East through East to Southerly aspect above 800 metres. The strong winds will continue to transport existing snow on to Southerly aspects where some deep unstable accumulations will exist. Avalanches and cornice collapse will occur. The avalanche hazard will remain High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: New snow above 400 metres on Sunday. ICING: Ice forming on rocks above 500 metres. COMMENT: Strong Northerly winds decreasing later on Monday. Ridges and buttresses have a cover of new snow. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SUN 13/2/05 It has been a very stormy day with strong winds and snow falling to valley level. Exposed slopes on N aspects have been stripped to older snow-ice but deep substantial deposits have formed in very sheltered locations on E through S to SW aspects above 650 metres. These deposits demonstrated very poor stability where tested. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK MON 14/2/05 The strong winds will ease slightly on Monday but there will be some further snowfall. Deep drifts will be found from 650 metres in very sheltered locations on E through S to SW aspects. Stability of these accumulations will remain poor and avalanches will occur. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Deep drifts in sheltered locations, exposed areas are scoured. ICING: Today's stormy conditions made it difficult to see anything let alone ice! COMMENT: Mountain footpaths will have deep drifting in places. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS SUN 13/2/05 Snow showers have fallen throughout the day with drifting on strong North- West winds. Natural avalanche activity was observed on steep South-East aspects above 800 metres. Weakly bonded windslab is present on North-East through East to South aspects. The avalanche hazard is High (Category 4). AVALANCHE HAZARD OUTLOOK MON 14/2/05 Little change is expected with additional snow showers accompainied by strong Northerly winds. Further drifting will continue with weakly bonded windslab persisting on North-East through East to South aspects above 800 metres where avalanches will occur. Triggering of fresh deposits will be probable with low additional loads. The avalanche hazard will be High (Category 4). Large unstable cornices will be present above steep sheltered aspects. CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow at all levels with difficult walking conditions. ICING: Buried at present COMMENT: Classic Creag Meagaidh avalanche conditions with upper slopes continuing to be loaded with fresh windslab. -------------------------------------------------------------------------------
