NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 18/3/02 It was a mild day with maximum temperature nearly 1 degree at the summit with rain in the afternoon. The middle and deeper snowpack has good stability. The moist surface snow has loose snow avalanche charateristics but no evidence of sluffing was observed. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK TUE 19/3/02 There will be a return to cooler conditions with snow overnight, easing during the day. The winds from the North-East and later North-West will deposit new slab on Southerly aspects above 900 metres. This new slab will not alter the stability of the deeper snowpack. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: The plateau is surviving the melt back. ICING: The cooling forecast is just in time. COMMENT: Localised and variable aspect cornices look rather weak. LOCHABER AVALANCHE HAZARD 1500 HRS MON 18/3/02 The mild conditions have continued with only light traces of fresh snow above 1100m. Snow stability is generally good on all aspects with the snowpack continuing to gradually thaw. Some wet surface instabilities are present but are generally restricted to the steepest slopes and gullies. The avalanche hazard is Moderate (Category 2). Remaining cornices prone to collapse. AVALANCHE HAZARD OUTLOOK TUE 19/3/02 Colder conditions will move into the forecast area from the North over the next 24hrs. Light amounts of snow and N winds will form shallow areas of soft slab on SE, S and SW aspects, although amounts are not expected to be significant. Any remaining wet snow instabilities will stabilise. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Becoming patchy, still good in N and E facing corries. ICING: Still good on many of the higher routes. COMMENT: Return to colder conditions should see things improve. GLENCOE AVALANCHE HAZARD 1500 HRS MON 18/3/02 Overnight rain with sleet at higher levels has given way to a bright dry day. The snowpack initially firmer above 900m has become soft and moist in most locations. Stability was found to be good on all but the steepest slopes and gullies where surface wet snow instabilities remain. The avalanche hazard is Low (Category 1). Cornices remain prone to collapse. AVALANCHE HAZARD OUTLOOK TUE 19/3/02 Cooler conditions for the period will aid consolidation of the existing snowpack with an icy crust forming at higher levels. Light snow will fall above 800m overnight with the possibility of the odd shower during the course of the day. Light Northerly winds will form isolated pockets of windslab around the tops of all sheltered gullies and in hollows mainly of a Southerly aspect. Accumulations are not expected to be extensive or of any significant depth and should generally be avoidable. The avalanche hazard in these areas will be Moderate (Category 2); elsewhere the snowpack will be stable. CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 500m. ICING: Will start to re-form on higher slopes overnight. COMMENT: Cold calm and dry for Tuesday should give a reasonable day for the hill. Cornices will remain weak. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS MON 18/3/02 The thaw has continued for another 24-hour period with the freezing level remaining around 1200 metres. The majority of the snowpack is soft and wet but relatively stable. In the deeper deposits that mostly exist on N to E aspects above 900 metres drier moderately bonded snow has survived the thaw. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 19/3/02 It will turn colder overnight with some light snow forecast. The wet snowpack will start to refreeze and a firm crust should be present by morning. New deposits will be light and should not drift heavily in the moderate NW winds. Where deposits do accumulate over a snow-ice base on steeper ground the avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy below 900 metres. ICING: Thawing today but turning colder tonight. COMMENT: Expect firmer conditions underfoot and water ice on paths tomorrow. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS MON 18/3/02 It has remained very mild with no further snowfall. The snowpack is wet and soft at the surface but relatively well bonded and stable on all aspects. Of more concern than the stability of snow slopes is the risk of cornice collapse with the freezing level well above the summits (+3.7 c at 900 metres). Ice is also collapsing particularly from the more exposed areas such as Pinnacle Buttress. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK TUE 19/3/02 With a return to colder weather the remaining underlying snowpack will freeze and consolidate on all aspects. However light snow showers on a moderate and variable Northerly wind will cause shallow and isolated areas of fresh windslab to form in the most sheltered of hollows on East to South aspects above 900 metres. These areas of fresh windslab will be very localised and easily avoidable. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Main cover above 600 metres on North to South-East aspects. ICING: Still fairly good in the gullies. Unfortunately the more exposed ice on Pinnacle Buttress has gone. COMMENT: Getting colder again. Take a day off work and get yourself up there! -------------------------------------------------------------------------------
