NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 16/3/05 Rain on strong warm South-Westerly winds has continued to penetrate the snow pack at all levels and on all aspects. The snow pack is moist to the ground on aspects below 950 metres. The weak old faceted layer deep in the snowpack remains and produced moderate releases during tests at 980 metres on a North- Westerly aspect. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK THU 17/3/05 Rain on strong Westerly winds will continue to affect the area. The snowpack will become more moist and weak layers that exist at depth will become more unstable. Avalanches are likely on mainly North- East through to South-Westerly aspects above 900 metres. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Very wet snow at all levels. ICING: Buttresses are black. COMMENT: Stonefall noted in Northern Corries. LOCHABER AVALANCHE HAZARD 1500 HRS WED 16/3/05 Warm, wet and windy conditions have continued overnight and during Wednesday. The snowpack has started to consolidate in many areas. Wet snow instabilities are generally restricted to steep aspects above 900m. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 17/3/05 Heavy rain and strong Westerly winds will continue overnight and during Thursday. The snowpack will continue to consolidate and stabilise in most areas. On Thursday, wet snow instabilities will be generally restricted to steep aspects above 950m. The avalanche hazard will be Moderate (Category 2). Any remaining cornices will be unstable and prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Wet snow at all levels. ICING: Freezing level around 2000m. COMMENT: Wet conditions expected to continue for a few days. GLENCOE AVALANCHE HAZARD 1500 HRS WED 16/3/05 Very mild and wet conditions have reduced the snowpack with the greatest accumulations now remaining in the higher Northern and Eastern corries. The remaining snowpack is soft wet and is generally stable on all but the very steepest slopes where wet snow instabilities remain. The avalanche hazard is Considerable (Category 3) in these areas. AVALANCHE HAZARD OUTLOOK THU 17/3/05 The mild and very wet conditions will continue overnight and through Thursday. The snowpack will be soft and wet with stability generally good on all but the steepest North to Easterly facing slopes and in sheltered gullies where wet snow instabilities will remain. Cornices will also remain prone to collapse. The avalanche hazard will be Moderate (Category 2) CLIMBING CONDITIONS SNOW DISTRIBUTION: Mainly above 900 metres in Northern and Eastern corries. ICING: Freezing level 2000 metres for period COMMENT: Mild wet and windy conditions look set to continue. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 16/3/05 There was a rapid rise in the freezing level overnight producing a period of avalanche activity. Many of the major Lochnagar gullies have avalanche debris at the bottom of them. The remaining wet snow is generally stable with a few isolated areas of moderately bonded snow persisting. These are mainly to be found in steeper sheltered locations on E to S aspects above 900 metres. Cornice collapse and falling rocks and ice remain a hazard. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 17/3/05 It will remain mild and wet with the freezing level at 2000 metres. The wet snow will continue to thaw fairly rapidly but will be generally stable. The main hazard will be from the collapse of any remaining cornices and ice pitches. Falling rocks are a serious threat during thaw periods. The avalanche hazard will be Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Significant loss but large quantities of patchy wet snow remain higher up. ICING: Buttresses are black, snow on ledges but thawing rapidly. COMMENT: Burns are flowing fast and are a serious proposition at present. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS WED 16/3/05 The heavy thaw conditions have resulted in a much depleted and very moist snowpack at all levels. Debris from transitional avalanches was noted on many slopes. Although the period of greatest instability has past, slopes which are overhung by remaining cornices are still a cause for concern. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK THU 17/3/05 The thaw conditions will continue. Further rain will add additional load to an already wet snowpack. Whilst the period of highest instability has already occurred, East through to South- East slopes, which are overhung by remaining cornices, will continue to be a cause for concern. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Mottled (or should it be bottled) and fast on its way to the Loch. ICING: Somehow has not all fallen down yet. COMMENT: Wellington territory on all approach paths -------------------------------------------------------------------------------
