NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS THU 25/1/96 Some additional moderately bonded windslab has been deposited high on some steep NW to N facing slopes and gullies where there is a Moderate (Category 2) hazard of avalanche. The remainder of the snowpack is stable. Local winds have scoured many areas of the Northern Corries below 1050m down to crusty windslab or hard neve. AVALANCHE HAZARD OUTLOOK FRI 26/1/96 Moderate to heavy snow showers on strong winds will result in accumulations of marginally to poorly stabilised windslab on SW to W-facing aspects. Some similar windslab deposits may develop at the heads of some sheltered NW to N-facing gullies. Considerable (Category 3) hazard of avalanche wherever new windslab accumulations are greatest. CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow-line remains at approx. 1000m. but may improve with more wintry conditions. Many plateau areas plastered with rime. ICING: Ice is developing but in general remains poor. Buttress routes still marginal but most easy gully lines in good condition on Thursday. COMMENT: Verglas on boulders leading to some difficulty when crossing corrie basins. LOCHABER AVALANCHE HAZARD 1500 HRS THU 25/1/96 Localised areas of unstable windslab have formed in sheltered locations and gullies, mainly on NW through NE aspects above 1000m. Largest accumulations are in Observatory Gully on Ben Nevis. Where this unstable slab exists the hazard remains Considerable (Category 3). AVALANCHE HAZARD OUTLOOK FRI 26/1/96 Fresh snow and easterly winds will further load sheltered locations with unstable windslab. These areas of fresh unstable snow will be present on slopes with a W through NE slope orientation, including the Red Burn gully on Ben Nevis. Where the fresh windslab exists the avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: A dusting of snow exists above 700m. ICING: Ice will continue to form at all levels. COMMENT: Crampons essential for all hill users. GLENCOE AVALANCHE HAZARD 1500 HRS THU 25/1/96 Light snow flurries during the day have increased the snow cover above 450m. The general snowpack is very thin and stable but the strong E to SE winds have deposited very localised areas of shallow windslab on sheltered N to W facing slopes. Where windslab overlies old snow ice in summit gullies and corrie headwalls the avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK FRI 26/1/96 Continuing fresh snow showers along with strong winds will continue to scour the existing snow cover and transport soft snow on to the sheltered SW to W facing slopes and all sheltered areas above 500m. Windslab will form in sheltered areas such as summit gullies and corrie headwalls. Where deeper deposits of windslab overlie the old patchy snow ice the avalanche hazard will increase to Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 300m. ICING: Ice on paths and rocks above 300m. COMMENT: Climbing conditions starting to improve with the new snow cover but most routes are still very thin. -------------------------------------------------------------------------------
