glencoe avalanche risk at 1500 on sun 9/1/94 there are layers of unstable windslab, accumulations greatest on ne to w facing slopes above 600m. avalanche risk category 4 (high) in these areas. large cornices have formed above n facing slopes. avalanche risk outlook for mon 10/1/94 thaw at all levels and heavy rain will give avalanche risk category 4 (high).avalanches will occur on ne to w facing slopes above 600m. and there is a danger of cornice collapse. summary. wet slab avalanches and cornice collapse will give avalanche risk category 4 (high). lochaber avalanche risk at 1500 on sun 9/1/94 areas of unstable hard slab exist on most lee slopes. this slab is poorly bonded to the underlying snow layers. the avalanche risk is category 3 (medium). avalanche risk outlook for mon 10/1/94 rain at all levels overnight and tomorrow will lubricate the existing slab and cause a deep instability within the snowpack. wet snow avalanches will occur on slopes where today`s unstable slab exists. the avalanche risk will rise to category 4 (high). cornices will be prone to collapse. summary. wet snow avalanches will occur due to heavy rain overnight. cornices will be prone to collapse. category 4 (high) northern cairngorms avalanche risk at 1500 on sun 9/1/94 storm conditions have resulted in fresh accumulations of hard windslab being deposited primarily on nw to n facing slopes. with the recent rise in freezing levels (1600m) a category 4 (high) risk of avalanche exists on high lee slopes and gullies where recent deposits overlie softer snow. any cornice development is likely to be unstable. avalanche risk outlook for mon 10/1/94 remaining mild with rain at all levels, winds reducing but continuing strong. freezing levels lowering slightly to 1500m. the moderate to heavy rain will further moisten the snowpack giving a risk of cornice collapse and wet snow slides on slopes where any significant accumulations exist. category 4 (high localised) risk of avalanche. summary. recent new snow deposits will remain unstable in thaw. a risk of cornice collapse exists. avalanche risk category 4 (high localised) -------------------------------------------------------------------------------
