Snow and Avalanche Report
Issued at 1500 hrs Thursday 31/10/2002
Exceptional early snowfalls have resulted in substantial 
accumulations of snow mainly above 600 metres in many 
highland mountain areas, particularly in the Cairngorms, Creag 
Meagaidh, Torridon and Perthshire areas.  Cornices exist 
above some slope aspects.  A slow thaw has led to a rise in 
the snow line in most areas, but this has been accompanied 
by the release of large full-depth slab avalanches on many 
aspects, some running to low altitude.  Several smaller slab 
releases have been reported in previous days.  The avalanche 
hazard in areas most affected is High (Category 4).

Avalanche Hazard Outlook Friday 1/11/2002
Generally warmer and stormier conditions will prevail during 
this period. Temperatures will rise over Thursday night, with 
rain forecast by midnight and freezing level above the summits 
by dawn.  This will lead to a period of extreme instability, which 
may persist as rain becomes heavier on Friday afternoon.  
Avalanches will occur on all aspects in areas most affected, 
with long runout likely.  Cornices will collapse.  Saturday will 
bring slightly cooler conditions and some stabilisation but 
stormy and wet conditions on Sunday will again result in 
instability of the remaining snowpack.  In the areas and 
periods of greatest instability the avalanche hazard will be 
Very High (Category 5). 

Regular Reporrts for 5 areas begin 15/12/2002
