NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS THU 3/2/00 A trace of new snow on mainly North-Westerly winds has led to some drifting and new slab build-up on North-East to South- East aspects above 1000 metres. Easy shears were observed in slab layers at 1100 metres. There are also some areas of new slab on North-facing crag aprons. Although hazard areas are localised and mostly avoidable, the avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK FRI 4/2/00 A little overnight snow on South-West winds will be followed by milder conditions and rain. The rise in temperature will gradually stabilise deep slab layers, but most recent deposits, mainly above 1000 metres on Easterly aspects and some North- facing crag aprons, will exhibit wet snow instabilities. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Still adequate cover in corries and on plateau. ICING: Good in N. Corries, but thaw imminent. COMMENT: Extensive water-ice on plateau. LOCHABER AVALANCHE HAZARD 1500 HRS THU 3/2/00 Fresh windslab last night has slowly turned to wet slab during the day. Significant deposits exist mainly on NE, E and SE aspects above 800 metres. Debris from surface slab releases observed on steep E aspects above 1050 metres on Aonach Mor. The avalanche hazard is Considerable (Category 3). Where the old snow exists, it is generally refrozen and stable. AVALANCHE HAZARD OUTLOOK FRI 4/2/00 Snow will turn to rain at all levels by Friday morning. The existing slab will become unstable as the thaw arrives. Wet snow avalanches will occur on steep NE, E and SE aspects above 1000 metres. The avalanche hazard will be High (Category 4). As the day progresses, the snowpack will gradually consolidate and stabilise. CLIMBING CONDITIONS SNOW DISTRIBUTION: Main accumulations remain in N and E facing corries. ICING: Snowpack thawing at all levels during Friday. COMMENT: Strong winds expected. GLENCOE AVALANCHE HAZARD 1500 HRS THU 3/2/00 Snow showers have deposited windslab on NE to SE facing slopes above 800 metres. Large expanses of hard old snow remain in corries with strips of soft slab in sheltered areas. Summit gullies and corrie headwalls with a more South-Easterly aspect contain more widespread accumulations. Weak bonds exist between several layers within deeper windslab. Avalanche hazard Considerable (Category 3). AVALANCHE HAZARD OUTLOOK FRI 4/2/00 Snow above 800 metres overnight followed by rain at all levels will increase the load on existing windslab. Corrie headwalls facing N through to E and sheltered summit gullies will contain areas of deep and increasingly unstable windslab. Avalanches are likely where summit gullies fan out. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow cover above 700m. ICING: Thawing ice above 600m. COMMENT: Severe gusts over ridges. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS THU 3/2/00 Localised areas of unstable snow exist in sheltered locations on mainly E to S aspects above 850 metres. Though only moderately bonded to the rest of the snowpack these recent deposits have not generally acquired much depth. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK FRI 4/2/00 Light snowfall overnight will have little effect on the snowpack. As the freezing level rises above the summits recent deposits that overlie harder snow ice will be destabilised. Where accumulations have acquired some depth on sheltered E to S locations above 850 metres the avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Mainly on high plateau areas and N to E corries. ICING: Mostly in deeper gully lines. COMMENT: Snow becoming soft at all levels on Friday. CREAG MEAGAIDH Report will be late. ------------------------------------------------------------------------------- CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS THU 3/2/00 Milder conditions with the freezing level above the summits has generally aided consolidation of the snowpack. However areas of deep unstable windslab still remains in gullies and hollows of a North through East to South-East aspect above 800 metres. Fresh cornices remain unstable through out this period. In these areas the avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK FRI 4/2/00 Generally milder conditions with rain on a South-Westerly airstream and freezing levels above the summits tomorrow will have little change on present conditions. Partially bonded windslab will be present in sheltered gullies and hollows of a North through East to South-East aspect above 800 metres. In these areas the avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Fresh snow above 700 metres, deepest accumulations on leeward slopes. ICING: Many holes have appeared in Post face and Inner Coire routes, thin in places. COMMENT:Warm and wet out today. -------------------------------------------------------------------------------
