NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SAT 8/1/05 There have been strong winds with heavy snow at all levels overnight. Deep accumulations of new slab have formed mainly on North-West through North to South-East aspects above 500 metres. Recently deposited layers showed extreme instability. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK SUN 9/1/05 Strong South-Westerly winds and snow showers will continue overnight followed by rain during the morning. Due to the rapid thaw and present instabilities avalanches will occur mainly on North-West through North to South-East aspects above 800 metres. The avalanche hazard will be high (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow at all levels with deep accumulations. ICING: Ground still unfrozen. COMMENT: Further unsettled weather in prospect. LOCHABER AVALANCHE HAZARD 1500 HRS SAT 8/1/05 Strong Westerly winds have formed areas of windslab mainly on North-East, East and South-East aspects above 900m. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK SUN 9/1/05 Overnight snow will turn to rain during Sunday with strong South-West winds. Wet snow avalanches will occur on steep slopes with a North-East, East and South- East aspect. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: A thaw is expected tomorrow as temperatures rise above the summits. ICING: Temperatures rising throughout the day. COMMENT: Remaining windy. GLENCOE AVALANCHE HAZARD 1500 HRS SAT 8/1/05 New snow is lying above 300 metres. Strong mainly Westerly winds have formed unstable windslab in sheltered locations. Greatest accumulations are to be found in summit gullies, sheltered hollows and on scarp slopes with a North through to South-Easterly aspect above 850 metres. Where deeper accumulations have formed stability is poor with very easy shears attained under test today. Avalanche hazard Considerable (Category 3) AVALANCHE HAZARD OUTLOOK SUN 9/1/05 Snow showers overnight will turn to heavy rain at all levels on Sunday morning giving a period of high instability where deeper accumulations of recent snow exist. Areas most affected will be in summit gullies, sheltered hollows e.g. exit slopes to Curved Ridge and slopes with a North through to South-Easterly aspect above 800 metres, where avalanches will occur. The avalanche hazard will be High (Category 4). CLIMBING CONDITIONS SNOW DISTRIBUTION: Above 300 metres. ICING: Freezing level rising to 1300 metres on Sunday. COMMENT: Windslab and cornices will require great caution. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SAT 8/1/05 Snow showers and strong W winds have led to new accumulations forming on NE to SE aspects above 900 metres. In sheltered locations deposits are achieving reasonable depth with poor stability particularly where they overlie older snow- ice. The avalanche hazard is Considerable (Category 3). Elsewhere cover is thin. AVALANCHE HAZARD OUTLOOK SUN 9/1/05 Snow showers will turn to rain as thaw conditions return again to the area. Deeper deposits of snow which are mainly to be found on NE to SE aspects above 900 metres will become increasingly unstable and avalanches are likely. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: A light general covering with deepest patches in N to E facing corries. ICING: Only starting to re-freeze but will again be subject to thaw conditions. COMMENT: Most of the thin snow cover will not survive the thaw when it arrives. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS SAT 8/1/05 Heavy snow showers have continued on gale force Westerly winds throughout the day with significant snow transport taking place. Deep accumulations of weakly bonded winslab are present on North-West through East to South aspects above 750 metres. Field tests produced very easy clean shears of fresh slab with numerous weak layers being present in depths of over 100cm. Observers triggered small loose snow avalanche on a North-East aspect at 850 metres. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK SUN 9/1/05 Overnight weakly bonded windslab will continue to build on North through East to South aspects above 750 metres with snow on strong Westerly winds. As snow turns to rain at all levels through the day wet snow instabilities will quickly form on all aspects above 750 metres. A period of high instabiliy will ensue with avalanches occuring on all the above mentioned aspects. The avalanche hazard will be High (Category 4). Freshly formed cornices will also be prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow at all levels. ICING: Running water still at 850 metres. COMMENT: Floods, mini tornadoes, blizzards and gale force winds and that was just driving here. Looks like winter's back again! -------------------------------------------------------------------------------
