NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 18-1-00 Continuous heavy drizzle has moistened and largely stabilised surface layers of the snowpack. Moderate shear tests were obtained on a South-East aspect at 1100 metres. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 19-1-00 Colder conditions will re-freeze the snowpack above 800 metres. A few light snow showers on North-Westerly winds will lead to some build-up on South-East aspects, but this is not likely to be significant. Most cornices have already collapsed. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Still substantial accumulations in corries and on plateaux above 850 metres. ICING: Improving with return to colder conditions. COMMENT: Prospect of better snow conditions. LOCHABER AVALANCHE HAZARD 1500 HRS TUE 18/1/00 The current mild conditions have generally consolidated the existing snowpack. Surface instabilities are present in some isolated locations on steep aspects exposed to solar radiation. The avalanche hazard is Low (Category 1). Large unstable cornices present. AVALANCHE HAZARD OUTLOOK WED 19/1/00 Little change is expected during the forecast period. The snowpack will remain generally stable at all levels. Surface instabilities will be present in some isolated locations on steep aspects exposed to solar radiation. The avalanche hazard will be Low (Category 1). Large unstable cornices will remain. CLIMBING CONDITIONS SNOW DISTRIBUTION: Main accumulations in N and E facing corries above 800m ICING: Large areas of snow ice remain in areas sheltered from solar radiation. COMMENT: Hazard of falling ice and rocks on steep ground. GLENCOE AVALANCHE HAZARD 1500 HRS TUE 18/1/00 Cold conditions overnight have left the snowpack generally firm and stable. Icy crusts exist on windward W to N slopes. Slopes with a sunny aspect contain areas of soft wet slab. Cornices above SE to E facing slopes are particularly unstable. As temperatures rise snow in summit gullies becomes less stable. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 19/1/00 Rain overnight and during Wednesday will make the snowpack soft and moist at all levels. Remaining cornices will be very unstable and prone to collapse. Soft slab lying on steep N to E facing corrie headwalls and in summit gullies will be potentially unstable. Elsewhere the snowpack will be soft but generally stable. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Wet snow above 650m. ICING: Thawing ice above 700m. COMMENT: Beware of falling cornices! SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 18/1/00 Snow continues to steadily thaw at all levels. A few areas of wet snow exist on steeper slopes but otherwise the snowpack is soft and well bonded. Remaining cornices are threatening to collapse. Rock and ice fall also continue to be a hazard. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 19/1/00 As the thaw gives way to colder conditions during the day the snowpack will begin to refreeze above 900 metres. Snow will gradually become well bonded but some areas may remain softer for a while. The avalanche hazard will be Low (Category 1). Remaining cornices will continue to be a hazard until refrozen. CLIMBING CONDITIONS SNOW DISTRIBUTION: Becoming patchy, most amounts in N to E corries. ICING: Continuing to thaw but will begin to refreeze later on Tuesday. COMMENT: Touring remains reasonable on Plateau areas. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS TUE 18/1/00 Continuing mild temperatures today have generally helped to stabilise the snowpack. Moderately well bonded windslab does remain however on North through East to South aspects above 800 metres, and here the avalanche hazard is Moderate (Category 2). Large cornices remain above many North through East to South-East aspects and these are very unstable and prone to collapse. AVALANCHE HAZARD OUTLOOK WED 19/1/00 Slightly colder temperatures tommorrow will have a general stabilising affect on the existing snowpack. However patches of moderately well bonded windslab remain on steep North through East to South aspects above 800 metres and in these areas the avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Still plenty above 700 metres; gullies, hollows and N and E facing slopes are holding the most. ICING: Main accumulations still hanging on; running with water though. COMMENT: -------------------------------------------------------------------------------
