NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 23/2/04 There have been snow showers overnight on fresh Northerly winds. This has led to localised build-up of slab mainly on East and South aspects. At 1100 metres on a South-East aspect tests showed unstable layers with very easy shears. Elsewhere the snowpack is stable. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 24/2/04 More snow is forecast on increasing North-Westerly winds with Summit temperatures remaining well below freezing. Areas of unstable slab will continue to build on East through South aspects above 950 metres where avalanches are likely. Other mainly North aspects will also have isolated pockets of slab on steep exit slopes, but elsewhere the snowpack is stable. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Large areas of soft snow on Southerly aspects. ICING: Slowly improving and the buttresses are white. COMMENT: A few good routes being done today. LOCHABER AVALANCHE HAZARD 1500 HRS MON 23/2/04 Light fresh snow has fallen overnight and during Monday. Although cover is improving, accumulations are not significant. The older snowpack remains well bonded and stable. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK TUE 24/2/04 A strong West to North-West airflow with snow overnight and during Tuesday will form fresh areas of unstable windslab in sheltered locations. Greatest accumulations will be at the tops of North East, East and South East facing slopes and gullies above 850 metres. This fresh windslab will be poorly bonded to the underlying frozen snow layers. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: A dusting of fresh cover above 600 metres. ICING: Freezing again at all levels tomorrow (Tuesday), after a brief rise on Monday night. COMMENT: Hopefully a return to much needed wintry conditions. GLENCOE AVALANCHE HAZARD 1500 HRS MON 23/2/04 Cool conditions are maintaining the old snowpack in a very stable condition. A light dusting of new snow above 900 metres and variable winds have formed isolated pockets of moderately bonded windslab in sheltered locations. These localised areas are mainly around the tops of North-East to Southerly aspects above 1000 metres. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 24/2/04 After a milder night conditions will become much colder on Tuesday. The old snowpack where exposed will remain hard and icy and will generally be stable. New snow and strong North-Westerly winds overnight and on Tuesday will form unstable accumulations of windslab in sheltered locations such as summit gullies and on North-East through East to South facing slopes above 850 metres, where avalanches are likely. Bonding to the underlying snow-ice will be poor particularly on steeper slopes. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Mainly in sheltered corries and gullies above 850 metres. Hopefully more on the way with blustery snow showers forecast for next few days. ICING: Freezing all levels on Tuesday. COMMENT: Old snowpack hard and icy in places. Fresh windslab and cornices will require great caution. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 23/2/04 There has been no new precipitation today but recent deposits remain poorly bonded. Unstable deposits exist in very sheltered locations on SE to SW aspects above 900 metres. The distribution of these deposits is limited but where they overlie snow-ice and buried surface hoar they are moderately to weakly bonded. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 24/2/04 Overnight snow will become more showery on Tuesday with strong winds that will continue to cause drifting of deposits. Moderately to weakly bonded deposits will be found on E through S to SW aspects above 900 metres. Avalanches are likely in steeper sheltered locations where new accumulations form over older snow ice. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Best cover across the South Cairngorms. Old snow in high N and E facing corries. ICING: Most lines are very thin. Watercourses remain the best option. COMMENT: Blizzard conditions at times on Tuesday. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 23/2/04 There has been no change from overnight conditions. The existing snowpack is sparse re-frozen and stable. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK TUE 24/2/04 Moderate snow will fall overnight with strong NW winds continuing on Tuesday. This will result in windslab development on North-East through East to South aspects above 850 metres. The avalanche hazard will increase to Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Sparse, patches only above 850m ICING: Lean COMMENT: Wintry for a spell. -------------------------------------------------------------------------------
