lochaber avalanche risk at 1500 on sat 26/2/94 large areas of unstable windslab are present mainly on nw facing slopes.however localised wind effects have also formed areas of unstable snow in sheltered locations, including the eastern corries of aonach mor. the avalanche risk is category 4 (high). avalanche risk outlook for sun 27/2/94 moderate snowfall and strong e winds will further load lee slopes and other sheltered locations with unstable windslab. avalanches will occur on slopes facing sw, w and nw. the avalanche risk is expected to remain category 4 (high). summary. strong e winds and snow, will form unstable slab on slopes facing sw, w and nw where avalanches will occur. category 4 (high). northern cairngorms avalanche risk at 1500 on sat 26/2/94 the snowpack in some areas of high, steep n and nw facing slopes and gullies is weakly stabilised. accumulations of deep, suspect windslab are present on most nw facing slopes, with areas of marginally stable windslab present at relatively low altitudes in some locations in coire an-t sneachda. category 4 (high localised) risk of avalanche. avalanche and cornice debris noted on slopes n of mess of potage in coire an t-sneachda. avalanche risk outlook for sun 27/2/94 a steady rise in freezing level to 600m should bring about some consolidation of the snowpack at lower altitudes on slopes and gullies of a n aspect. however, any new windslab that forms on sw through to n facing slopes as a result of moderate to heavy snow with e then ne winds, will show weak stability. category 4 (high localised) risk of avalanche high on some slopes and gullies of a sw to n aspect where avalanches will occur. summary. current category 4 (high localised) risk of avalanche maintained on slopes and gullies of a sw to n aspect where avalanches will occur. glencoe avalanche risk at 1500 on sat 26/2/94 above 750m areas of soft windslab exist, this is lying on an icy base mainly on sw through to n facing slopes. avalanche risk category 3 (medium localised). avalanche risk outlook for sun 27/2/94 snowfall overnight and into sun. and strong e winds will deposit windslab on sw through to n facing slopes, particularly in gullies and hollows above 700m. avalanches are likely in these areas. avalanche risk category 3 (medium). summary increasing avalanche risk on sw through to n facing slopes above 700m where avalanches are likely. avalanche risk category 3 (medium). -------------------------------------------------------------------------------
