NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 19/1/04 There has been heavy rain at all levels, and strong Westerly winds during the past 24 hours. After an initial period of instability the rain soaked snow is reasonably well bonded. However cornices and areas of steep soft snow show signs of instability. These can be found on all aspects, but especially North and East aspects above 950 metres. The avalanche Hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 20/1/04 The weather will remain mild during the forecast period with heavy rain. The snow pack will continue to thaw rapidly. Stability will improve in these conditions. However instabilities will remain in any large areas of steep soft snow above 950 metres. Cornices will be prone to collapse. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Large areas of deep slush on plateau. ICING: The buttresses are black, but small areas of ice remain. COMMENT: Winter conditions disappearing fast in very mild weather. LOCHABER AVALANCHE HAZARD 1500 HRS MON 19/1/04 After an initial period of instability the wet snowpack is gradually starting to consolidate but areas of unstable wet snow are still present on many aspects. Greatest accumulations are on North through East to South East aspects above 1000m, notably steep slopes, scarp slopes and crag aprons. The avalanche hazard is Considerable (Category 3). Cornices are prone to collapse. Wet avalanche debris observed on the above aspects, Aonach Mor. AVALANCHE HAZARD OUTLOOK TUE 20/1/04 The thaw conditions will continue for the next 24hrs. The existing wet snowpack will become saturated at all levels. Wet snow instabilities will be present, mainly on steep North through to East to South East aspects above 1000m.The avalanche hazard will be Considerable (Category 3). Any remaining cornices will remain prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Best cover in N and E facing corries. ICING: Freezing above the summits. COMMENT: Hazard of rock and ice fall in thaw conditions. GLENCOE AVALANCHE HAZARD 1500 HRS MON 19/1/04 Wet and mild conditions have saturated the snowpack releasing numerous wet snow avalanches mainly on North and East facing slopes above 850 metres. Cornice debris also noted below these aspects. The avalanche hazard is Considerable (Category 3) AVALANCHE HAZARD OUTLOOK TUE 20/1/04 The mild conditions will continue with heavy rain at all levels overnight and on Tuesday. The snowpack will remain in a saturated state maintaining wet snow instabilities on the steepest slopes and gullies. Large cornices will also remain prone to collapse threatening slopes below. Elsewhere the snowpack will be soft and wet but general stability will continue to improve. The avalanche hazard will be Considerable (Category 3) CLIMBING CONDITIONS SNOW DISTRIBUTION: Wet snow above 700 metres. ICING: Thawing all levels. COMMENT: Poor outlook. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 19/1/04 With temperatures rapidly rising last night there has been a period of instability with avalanche debris noted on most slopes at Lochnagar. Significant snow loss has occurred especially where cover was superficial. Moderately bonded deposits are to be found in deeper accumulations on steep slopes on mainly N through E to SE aspects. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 20/1/04 The thaw will continue tomorrow leaving the remaining snow wet but generally well bonded. On steeper slopes on mainly N through E to SE aspects moderately bonded deposits will be found in deeper accumulations above 900 metres. The avalanche hazard will be Moderate (Category 2). Remaining cornices will have the potential to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Significant snow loss has occurred with superficial deposits thawing rapidly. ICING: Faces black, ledges holding snow and main gully lines complete in Lochnagar. COMMENT: Cornice collapse and rock fall will continue to provide a hazard tomorrow. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 19/1/04 Milder temperatures and moderate to heavy rain have seen a period of high instability: debris from loose wet snow avalanches is evident below 800 metres on North East through to East facing slopes. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK TUE 20/1/04 Although the period of highest instability is likely to have passed, mild temperatures and heavy rain will continue to moisten the snowpack and maintain poor bonding on steepest North through East to South East aspects above 800m. The avalanche hazard will remain Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Thaw conditions leading to a much depleted snow cover. None below 600 metres. ICING: The little that was is fast disappearing. COMMENT: Any remaining cornices should be treated with extreme caution. -------------------------------------------------------------------------------
