glencoe avalanche risk at 1400 on thu 30/12/93 there are layers of windslab lying on a refrozen base, greatest accumulations on slopes with a northerly aspect above 800m. avalanche risk category 3 (medium). avalanche risk outlook for fri 31/12/93 further snow showers and strong wind s veering nw will give some accumulation of fresh windslab mainly on n through to e facing slopes above 800m. avalanches are likely in these areas. avalanche risk category 3 (medium). summary. the avalanche risk category will remain 3 (medium) with new windslab on n and e facing slopes. northern cairngorms avalanche risk at 1400 on thu 30/12/93 dry, sunny and cold conditions with light to moderate w or nw winds have produced only small amounts of new windslab. slopes of most aspects have been scoured, but a category 3 (medium localised) risk of avalanche exists on e facing slopes where the largest accumulations of old windslab persist. avalanche risk outlook for fri 31/12/93 the forecast light snow showers and s, later nw, light to moderate winds may add some thin accumulations of windslab to high n through to se facing slopes and sheltered gully areas. category 3 (medium localised) risk of avalanche wherever windslab build-up is greatest. summary. new thin windslab build-up on n through to se facing slopes will give a category 3 (medium localised) risk of avalanche in those areas. lochaber avalanche risk at 1400 on thu 30/12/93 large areas of unstable windslab exist, mainly on slopes with a n and e aspect. the avalanche risk is category 4 (high). avalanche activity observed in the eastern corries of aonach mor. avalanche risk outlook for fri 31/12/93 continuing snow showers with s winds veering nw will further load existing unstable areas. avalanches will occur on n,e and s facing slopes. the avalanche risk is expected to remain at category 4 (high). summary. moderate snow showers with s to nw winds will continue to load existing unstable slopes. category 4 (high). -------------------------------------------------------------------------------
