NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 21/1/04 The freezing level was at about 1200 metres today with light winds and drizzle. The snowpack, where sampled at 1100 metres on a Northerly aspect, is well bonded with various densities of moist coarse grained layers. Evidence of recent rockfall was noted. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 22/1/04 The freezing level is forecast to stay persistently high, up to 2400 metres. Light to moderate rain will fall on an already rain soaked snowpack. Moderate winds will be initially from the South-West then South, finally becoming Westerly. The snowpack stability in areas of deeper cover will be good. Rockfall will be a hazard and glide cracks may appear. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Some of the main gullies are still complete. ICING: Leaking. COMMENT: Consideration should be given to the removal of crampons on the fragile bare ground at the rim of the corrie. LOCHABER AVALANCHE HAZARD 1500 HRS WED 21/1/04 Thaw conditions have continued overnight and today with moist South-Westerly winds. This has depleted the snowpack further. Wet snow instabilities are still present on steep North through East to South East aspects above 1000 metres. Elsewhere the snowpack is generally stable. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 22/1/04 Further rain overnight and during Thursday will continue to reduce the snowpack as freezing levels remain well above the summits. The existing wet snow instabilities will remain on steep North through East to South-East aspects above 1000 metres. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Little snow remaining below 800m. ICING: Very much non-existent. COMMENT: The warm cycle looks set to continue until the end of the weekend. GLENCOE AVALANCHE HAZARD 1500 HRS WED 21/1/04 Slightly cooler and drier conditions today have slowed down the rate of thaw. Much of the snowpack at lower levels has now gone with the best cover remaining in the higher North and East facing corries and gullies. 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 THU 22/1/04 The mild conditions will continue with light to moderate rain. Surface wet snow instabilities may exist on the steepest slopes and large cornices will also remain prone to collapse threatening slopes below: these slopes will mainly be of Northern and Easterly aspects above 900 metres. Elsewhere the snowpack will be soft and wet but general stability will continue to improve. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Wet snow above 800 metres. ICING: Thawing all levels. COMMENT: Poor outlook. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 21/1/04 The skies cleared for a period last night with temperatures becoming low enough for the surface layers of the patchy remaining snow to firm up. Cover is now restricted to extensive patches of well bonded snow. Exposed areas are mostly stripped with greater remnants being found in high N to E facing corries where the main gully lines are holding snow. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK THU 22/1/04 It will be milder with light rain . Surface layers will be softer but stability will remain good. The remaining patchy snow will be well bonded on all aspects with greatest accumulations being found in high N to E facing corries. The avalanche hazard will be Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Limited to extensive patches with high N to E facing corries holding most snow. ICING: Buttresses are black. Main gullies are holding on to snow. COMMENT: Unlikely to cool down until Sunday. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS WED 21/1/04 Thaw conditions have continued with light rain on moderate Westerly winds. Wet snow instabilities persist on steep North through East to South-East aspects above 850 metres. Elsewhere the snowpack is soft and moist but generally well bonded and stable. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 22/1/04 Thaw conditions will continue on gale force Westerly winds with rain easing by morning. Wet snow instabilities will persist on all aspects but particularly on steep North through East to South-East slopes above 800 metres. The avalanche hazard will be Moderate (Category 2). A residual hazard from falling cornice remnants and rock will exist from steep ground. CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy cover above 800 metres. ICING: None at the moment. COMMENT: Falling cornice remnants and rock remain a hazard in continued thaw! -------------------------------------------------------------------------------
