NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 2/2/99 The snowpack is generally well consolidated and stable with surface layers becoming moist during the current mild conditions. As with all thaw periods, cornices are best avoided, particularly above steep E to SE gully tops where largest cornices remain. Avalanche hazard remains Low (Category 1). AVALANCHE HAZARD OUTLOOK WED 3/2/99 Snow overnight turning to rain, accompanied by strong SW to W winds will result in a period of instability of newest deposits. Loose wet snow slides from these deposits are likely, primarily on steep NE to E facing aspects, where greatest accumulations have developed. Avalanche hazard Considerable (Category 3) in these locations. CLIMBING CONDITIONS SNOW DISTRIBUTION: Remains reasonable in plateau areas despite diminishing with thaw conditions. ICING: Buttresses now black. Ice still in deepest recesses. Quality very variable. COMMENT: Surface instabilities from newest deposits with the arrival of any rain. LOCHABER AVALANCHE HAZARD 1500 HRS TUE 2/2/99 Mild temperatures are continuing to consolidate the snowpack. The snowpack is generally stable. On some steep slopes, areas of moderately well bonded snow are still present. In these locations the avalanche hazard is Moderate (Category 2). Large cornices are still present, mainly above N, NE and E aspects. AVALANCHE HAZARD OUTLOOK WED 3/2/99 Light snow showers are expected briefly overnight and a return to very mild conditions again by Wednesday morning. The snowpack will continue to consolidate at all levels. Localised areas of moderately bonded snow will remain on steep slopes. In these locations, the avalanche hazard will be Moderate (Category 2). Elsewhere the snowpack will be stable. Remaining cornices will be prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: General snow cover above 750m. ICING: A brief cold spell expected overnight and a return to mild conditions during Wednesday. COMMENT: Gusty winds expected during Wednesday. GLENCOE AVALANCHE HAZARD 1500 HRS TUE 2/2/99 A warm blustery SW airflow has rendered the snowpack soft and moist at all levels. Though generally well bonded, areas of moderately bonded wet slab exist in summit gullies and on steep corrie headwalls facing N to E. In these areas the avalanche hazard is Moderate (Category 2). Cornices remain unstable in the mild conditions. AVALANCHE HAZARD OUTLOOK WED 3/2/99 The mild conditions will persist with rain well above the summits. The snowpack will remain soft and moist at all levels. Large cornices will become very unstable with the potential of triggering avalanches on slopes below. In summit gullies containing deep wet slab the avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow cover above 550m. ICING: Thawing ice above 750m. COMMENT: Freezing level well above summits: ice falling from buttresses. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 2/2/99 Snow conditions remain much the same as recent days with the snow firm and stable on all aspects. Where cornices remain they continue to be a hazard. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK WED 3/2/99 After some overnight light snow, rising freezing levels and light rain will continue to thaw the snowpack at all levels. On sheltered slopes of N to E aspects where accumulations are greatest they will be moderately well bonded. Remaining cornices will be prone to collapse. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Still good above 900m although starting thin out in some areas. ICING: Any ice is a little wet and starting to soften. COMMENT: Likely to be quite windy on the tops. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS TUE 2/2/99 With temperatures remaining mild the snowpack has continued to consolidate and is generally well bonded and stable. However wet surface layers present on steep N through to SE slopes above 800m are only moderately well bonded. Remaining cornices above these slopes are still very unstable and are also prone to collapse. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK WED 3/2/99 With the freezing level well above the summits, light rain and severe storm force westerly winds the snowpack will continue to consolidate tomorrow. However additional amounts of moisture may cause wet snow slides on steep slopes of a NW through to S aspect above 800m and will weaken any remaining cornices. In these areas the avalanche hazard will be Considerable (Category 3). Elsewhere the snowpack will be soft but well bonded and stable. CLIMBING CONDITIONS SNOW DISTRIBUTION: Good cover above 750m, although becoming patchy on some aspects. ICING: Plenty of ice still, thawing at the moment but may improve as temperatures fall later in the week. COMMENT: Cornice collapse can trigger avalanches - beware of run out zones! -------------------------------------------------------------------------------
