NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 1/3/04 High pressure remains with light winds, clear skies and summit temperatures below zero. Northerly aspects above 1000 metres are mainly scoured with small pockets of unstable slab. The main accumulations of snow are on Southerly aspects. Where tested at 1060 metres on a South-East aspect several layers sheared easily especially the old depth hoar above the snow-ice base layer. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 2/3/04 The cold dry weather will continue with moderate South- Westerly winds. Fresh slab will accumulate mainly on North Easterly aspects above 1000 metres. Deep slab instabilities will remain on Southerly aspects above 950 metres especially on steep convex ground. Isolated pockets of this instability will exist on other aspects. Sun warming at lower levels will cause some surface weakness. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Very good ski touring on the plateau with a few rogue rocks. ICING: The buttresses are very white with limited ice. COMMENT: Watch out for those deep slab instabilities! LOCHABER AVALANCHE HAZARD 1500 HRS MON 1/3/04 Monday has been sunny and cold, with little change to the existing snowpack. Localised pockets of shallow windslab are present. Accumulations are mainly restricted to the tops of South-East, South and South-West aspects and are generally avoidable. Shallow surface instabilities are present on steep slopes exposed to solar radiation. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 2/3/04 Little change is expected overnight and during Tuesday. Localised areas of shallow windslab will remain at the tops of South-East, South and South-West aspects. Shallow surface instabilities will develop on any steep slopes exposed to sun. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Best cover remaining in high North and East facing corries. ICING: Remaining cold; ice will start to thaw at lower levels in the sun. COMMENT: Strong South-West winds expected. The old snowpack will remain well frozen. Ice axe and crampons essential. GLENCOE AVALANCHE HAZARD 1500 HRS MON 1/3/04 Cold settled conditions have maintained very good stability of the general snowpack with a widespread frozen surface. Isolated areas of weakly bonded windslab exist in the most sheltered of areas mainly above 950 metres. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 2/3/04 It will remain cold overnight with freezing levels rising to 800 metres during the course of Tuesday. Much of the snowpack will remain firm, icy and will be very stable. Dry conditions will prevail but strengthening South-Westerly winds will re- distribute snow forming areas of windslab in sheltered gullies and on North to East facing slopes above 900 metres. These deposits are not expected to be extensive but bonding to underlying snow-ice will be moderate on steeper slopes. Slopes exposed to the sun will soften giving some surface instabilities later in the day. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Mainly in sheltered corries and gullies above 850 metres. Widespread snow ice. ICING: Ice on rocks and paths above 400 metres. COMMENT: Snowpack hard and icy, crampons and ice axe essential. Some good climbing conditions but mainly limited to the easier snow routes and frozen watercourses. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 1/3/04 It has been a dry and sunny day. The recent deposits on SE to SW aspects have continued to consolidate and are moderately well bonded. Solar warming is causing small wet sloughs on steeper ground mainly from cornices. The avalanche hazard is Moderate (Category 2). Other aspects have either thin cover or old frozen snow-ice. AVALANCHE HAZARD OUTLOOK TUE 2/3/04 After a cold night it will be another dry day with the freezing level rising to 800 metres. Moderately well bonded deposits will be found on SE to SW aspects above 800 metres. Steeper slopes exposed to the sun will demonstrate some surface instability with small wet sluffs possible as the day progresses. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Mostly wind scoured slopes with deeper drifts on SE to SW aspects. ICING: Lean conditions persist. Thawing at lower levels today especially on South aspects but cold again tonight. COMMENT: Linked ski touring available for the keen. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 1/3/04 Isolated pockets of soft slab persist on shaded mostly Easterly aspects above 900 metres. Field tests showed marginal stability with easy surface shears in the most recent deposits that lie over old snow-ice. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 2/3/04 It will remain settled with no new precipitation. An overnight frost will re-freeze snow melt. Daytime sun will gradually thaw snow at lower elevations. Pockets of soft slab will persist in heavily shaded North East to East aspects, The avalanche hazard will be Moderate (Category 2). Sun-affected cornices will remain suspect during warmer daytime temperatures. CLIMBING CONDITIONS SNOW DISTRIBUTION: Pockets of drifted snow below 850 metres with a light general cover on tops. ICING: Some development but no major improvement. COMMENT: High level walking /touring still the best option for winter sport. -------------------------------------------------------------------------------
