NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS THU 17/12/98 Rain and thaw conditions throughout the period, at all levels, have depleted and moistened remaining small pockets of snow. Avalanche hazard Low (Category 1). AVALANCHE HAZARD OUTLOOK FRI 18/12/98 Colder conditions will prevail, with some light snow down to 300m for a period. Precipitation will not be significant and the avalanche hazard will remain Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Rain at all levels has depleted any cover to little more than isolated patches. ICING: Thaw conditions on Thursday. COMMENT: Colder weather awaited with anticipation of things yet to come! LOCHABER AVALANCHE HAZARD 1500 HRS THU 17/12/98 A thaw at all levels has reduced the snowpack to localised areas of old snow. These accumulations are generally restricted to N and E facing corries above 1100m.The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK FRI 18/12/98 Colder conditions will bring snow showers above 600m overnight and during Friday. Some localised fresh snow deposits are expected, but these will be restricted to sheltered locations on N, NE and E aspects. New snow accumulations are not expected to affect the existing avalanche hazard. The avalanche hazard will remain Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Fresh snow expected down to 600m overnight. ICING: Freezing level lowering overnight to 600m and rising again on Friday to around 1000m. COMMENT: Winds moderating. GLENCOE AVALANCHE HAZARD 1500 HRS THU 17/12/98 Heavy rain at all levels and the strong SW winds have thoroughly saturated the small isolated patches of old snow. Above 930m in deep sheltered gullies small pockets of wet snow still exist. These deposits are not signifcant or of any great depth. No Avalanche hazard Category issued. AVALANCHE HAZARD OUTLOOK FRI 18/12/98 Light snow showers can be expected during Thursday night above 900m and continuing through Friday morning down to 600m. These new deposits are generally expected to be light but where deeper deposits form in sheltered summit gullies the avalanche hazard will increase. In these locations the avalanche hazard will be Low (Category1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Isolated patches above 930m. ICING: None . COMMENT: Limited winter conditions at present. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS THU 17/12/98 Very mild conditions have led to a rapid thaw of existing snow patches with some old harder areas remaining. Snow patches are mainly to be found on N aspects above 950m. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK FRI 18/12/98 Colder conditions with some snow will leave fresh deposits on sheltered slopes and gullies on NE aspects. Some unstable areas will exist above 950m where new deposits overlie old harder snow but the avalanche hazard will remain Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Very patchy. ICING: None, but possible as temperatures start to drop. COMMENT: Freezing level will rise during through morning before falling in afternoon. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS THU 17/12/98 Overnight thaw and heavy rain have further depleted the remaining snowpack. Largest areas remain in the upper sections of the deeper gullies of a N to E facing aspects. The remaining snowpack is stable. Low (Category 1) hazard of avalanche. AVALANCHE HAZARD OUTLOOK FRI 18/12/98 Moderate snowfall on a fresh SW/W wind will cause accumulations of windslab to form at the top of sheltered gullies and hollows of a N through to SE facing aspect above 850m. This windslab will only affect areas where it overlies old existing snow. There will be a Moderate (Category 2) hazard of avalanche in these localised areas. CLIMBING CONDITIONS SNOW DISTRIBUTION: Very patchy above 900m. ICING: Non existent. COMMENT: Hopefully there will be a return to more wintry conditions. -------------------------------------------------------------------------------
