Snow and Avalanche Report

Issued at 15.30 hrs. Wednesday 8/12/1999
Continued snow showers have led to some new build-up in corries
and other accumulation zones above 850 metres in most Highland
mountain areas. Rain at lower levels has seen the snowline in
most regions rise to between 700 and 800 metres, 500 metres in
the North Cairngorms.  Main accumulations in most ranges are on
North and East facing slopes above 850 metres, with Lochaber and
the  Cairngorms again holding most snow. Localised remnants of
old snow-ice underlie the new slab in these high locations. The
avalanche hazard in these areas is Category 3 (Considerable).

Avalanche Hazard Outlook Thursday 9/12/1999
Freezing conditions  on the highest summits will
lead to some additional slab build-up on higher North and
Easterly aspects, mostly above 850 metres. Lochaber and the
Cairngorms are again most stongly indicated. Some significant
accumulations will exist, and there will be drifting in strong
winds. Instabilities will be present where new accumulations are
greatest on steep mainly North and Easterly aspects, especially
where re-frozen old snow underlies. A Category 3 (Considerable)
hazard of avalanche will prevail in these localised areas.
