NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS FRI 23/1/04 The freezing level remained above the tops with strong Westerly winds and some afternoon rain. This made for little appreciable change to snowpack stability which is good. The snow profile was done on an Easterly aspect at 1130 metres in 130 centimetres of snow. There was one dry layer near the base of the snowpack. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK SAT 24/1/04 Light snow will fall with the freezing level at 750 metres. The winds will be Westerly. Above 900 metres there will be small slabs developing on Easterly aspects. With the snow falling during a cooling trend there will be a reasonably good bond to the old snow surface. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow surface in places supports 40kg but not 80kg; with foot penetration up to 20 cm. ICING: Hopefully a rebuilding cycle in sight COMMENT: Avalanche hazard can increase just as quickly as snow arrives. LOCHABER AVALANCHE HAZARD 1500 HRS FRI 23/1/04 The continuing thaw conditions are gradually consolidating the existing snowpack. Snowpack stability is generally good. The avalanche hazard is Low (Category 1). Remaining cornices are still unstable. AVALANCHE HAZARD OUTLOOK SAT 24/1/04 Colder conditions and snow showers are expected with moderate W winds. Fresh snow accumulations will generally be restricted to the tops of slopes and gullies with a North-East, East and South-East aspect above 800m. The avalanche hazard will be Considerable (Category 3). The existing old snowpack will re-freeze and become stable. CLIMBING CONDITIONS SNOW DISTRIBUTION: Fresh snow expected down to 700m on Saturday. ICING: Colder conditions should start ice formation again. COMMENT: Old windblown snow will become hard frozen at all levels. GLENCOE AVALANCHE HAZARD 1500 HRS FRI 23/1/04 Cooler dry conditions overnight aided consolidation of the snowpack at higher levels. Light rain today has softened and moistened the snowpack. The general stability of the remaining snow cover is good in most areas, but isolated surface wet snow instabilities remain on the steepest slopes and gullies. Some of these areas, predominantly North and East facing slopes above 900 metres are threatened by potentially weak cornices. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK SAT 24/1/04 Colder conditions will return overnight with moderate snowfall and strong Westerly winds. The old moist snow cover will firm up as freezing levels lower to 700 metres. Where deep windslab forms on top of older snow-ice bonding will be poor, mainly on slopes of a North-East to South-Easterly aspect above 750 metres, where avalanches are likely. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: New snow on the way. ICING: Ice will start to re-form above 700 metres. COMMENT: Frequent snow showers expected down to 400 metres. Windslab and fresh cornices will require great caution. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS FRI 23/1/04 There has been no change to the current situation with the patchy snow remaining well bonded and stable. There is very little snow below 900 metres with more extensive patches above this level. High N to E facing slopes are holding most snow with deeper deposits in more sheltered locations. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK SAT 24/1/04 It will become much colder overnight with light snow showers forecast for Saturday. The patchy remaining snow will re-freeze and fresh deposits will form in sheltered locations on NE to SE aspects. These new deposits are not expected to be deep but they will demonstrate limited stability where a snow-ice base exists. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Large patches above 900 metres with high N to E facing corries holding most snow. ICING: None observed. COMMENT: Old snow should be very firm by morning. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS FRI 23/1/04 Dry and cooler overnight temperatures have aided snowpack stability. The snowpack is generally well bonded and stable on most aspects. Wet layers are still present in deeper snow on North through East to South-East aspects above 750 metres. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK SAT 24/1/04 Dry, colder conditions at first will further aid remaining snowpack stability. Snow by morning on strong Westerly winds will form fresh windslab on North through East to South-East aspects above 850 metres. Deepest accumulations will be found in sheltered gullies, hollows and at the tops of steep scarp slopes with marginal bonding to existing old snow deposits. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy above 750 metres. ICING: None at present, but will reform in colder temps. COMMENT: At last a return to more seasonal conditions! -------------------------------------------------------------------------------
