glencoe avalanche risk at 1400 on mon 27/12/93 there is a widespread stable windcrust.there are however areas of unstable windslab mainly on slopes and gullies of a northerly aspect above 750m.avalanche risk category 3 (medium)in areas of windslab. avalanche risk outlook for tue 28/12/93 severe gale to storm force s winds and heavy snowfall overnight will significantly load all slopes and gullies of a northerly aspect with unstable windslab.avalanches will occur in these areas. avalanche risk category 4 (high). summary. avalanche risk increasing to category 4 (high) due to heavy snowfall and high winds. northern cairngorms avalanche risk at 1400 on mon 27/12/93 old windslab on se facing slopes still shows signs of instability. stronger than forecast s winds have also re-distributed snow onto north facing slopes and gullies. a category 3 (medium localised) risk of avalanche on steep slopes where any significant slab accumulation exists. avalanche risk outlook for tue 28/12/93 a forecast of gale force southerly winds and snow (fl-all levels going to 800m) will lead to a build up of windslab on north facing slopes and gullies. avalanches will occur in these areas. category 4 (high) risk of avalanche. summary. a category 4 (high) risk of avalanche will exist, mainly on slopes of a northerly aspect. lochaber avalanche risk at 1400 on mon 27/12/93 areas of unstable slab exist mainly on north and west facing slopes. on slopes which are not exposed to the sun, a weak layer is present in the snowpack. the avalanche risk is category 3 (medium) avalanche risk outlook for tue 28/12/93 heavy snow overnight accompanied by strong s-sw winds will produce large areas of unstable windslab, particularly on north-easterly aspects. wet snow avalanches will occur below 900m and slab avalanches will occur above 900m, especially on north-easterly aspects. the avalanche risk will increase to category 4 (high). summary. heavy snow,strong s-sw winds and a rising freezing level will produce an unstable snow-pack.avalanche risk increasing to category 4 (high) -------------------------------------------------------------------------------
