NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 1/2/99 A slow thaw has moistened the snowpack in all locations. Stability is good in most places though cornices over E to SE aspects still prone to collapse. Low (Category 1) hazard of avalanche. AVALANCHE HAZARD OUTLOOK TUE 2/2/99 Steady slow thaw will continue to moisten the snowpack and stability will remain good in most places. Additional rainfall will maintain the risk of cornice collapse primarily over steep E to SE-facing slopes and gullies. The avalanche hazard will be Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Coverage on all plateaux areas remains excellent despite slow thaw. ICING: Thickest ice development still OK but thinner stuff wet and a bit rotten. Buttresses blacker. All popular gullies complete and remain well filled (with snow and people!) COMMENT: Good mountain conditions on Monday; mild weather forecast. LOCHABER AVALANCHE HAZARD 1500 HRS MON 1/2/99 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 TUE 2/2/99 The mild conditions are expected to continue overnight and during Tuesday. 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 cover of wet snow remaining above 750m. ICING: Freezing level remaining above the summits. COMMENT: Winds increasing during Tuesday. GLENCOE AVALANCHE HAZARD 1500 HRS MON 1/2/99 Colder conditions overnight have led to a firm snow crust this morning. Rising temperatures during the day have softened the snowpack again. Sheltered summit gullies and steep N to E slopes above 600m contain snow which is moderately bonded and in places threatened by large unstable cornices. Avalanche hazard Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 2/2/99 Light rain overnight and during Tuesday will render the snowpack soft and moist at all levels. Large cornices will become very unstable threatening N to E facing slopes and summit gullies below. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow cover above 550m. ICING: Thawing ice above 750m. COMMENT: Freezing level and light rain above summits during Tuesday, fingers crossed for a freeze on Wed. ! SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 1/2/99 The snowpack continues to be firm and stable at all levels. Surface layers of the snow have been softened by the sun on E to SE aspects, as have cornices, which are unstable. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK TUE 2/2/99 The morning will see snow hard and icy, gradually becoming a little softer during the day particularly with the arrival of some light rain. The avalanche hazard will remain Low (Category 1), but where cornices exist they will continue to be unstable. CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy up to around 900m after which is good but areas are getting a bit thinner. ICING: Some ice remains despite warmer air temperatures. COMMENT: After a cold start the freezing level will be above summits. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 1/2/99 With temperatures remaining mild the snowpack has continued to consolidate and is well bonded and stable on most aspects. 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 prone to collapse. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 2/2/99 A moist SW airflow will bring a continuation of the mild conditions tomorrow, although ground frost is likely tonight. Patchy rain and drizzle will weaken the bonding of remaining cornices and surface layers on steep slopes of a NW through to SE aspect above 800m. 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 700m, although patchy on some aspects. ICING: Plenty of ice still in Coire Ardair, but soft and falling off in the continuing thaw. COMMENT: Cornice collapse can trigger avalanches, beware of run out zones! -------------------------------------------------------------------------------
