NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 13/2/01 A maximum temperature of -2 degrees at the summit of Cairngorm has contributed to a tightening in of the snowpack and settlement over time since the storm. Moderate SW winds are still moving snow on to NE aspects above 1000 metres. In field tests easy shears are still evident. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK WED 14/2/01 Another dry day is forecast for the region. Pockets of instability will persist due to the deep weakness but generally snowpack stability will be fair to good. The main aspect and elevation of concern will be North and East above 900 metres. The avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Full cover on plateau, some icy sections. ICING: Sweep off the snow and there's a little more ice down there. COMMENT: For the keen observer mature depth hoar is still available to look at in numerous locations. LOCHABER AVALANCHE HAZARD 1500 HRS TUE 13/2/01 The current settled conditions have had little effect on the existing snowpack. Localised areas of windslab are present, but these are generally restricted to scarp slopes above 1100 metres with a NE and E aspect. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 14/2/01 The settled weather is expected to continue throughout the forecast period. Little change is expected to the existing snow conditions. Areas of unstable snow will generally be restricted to scarp slopes above 1100 metres with a NE and E aspect. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Good general cover above 700m. ICING: Ice melting where exposed to the sun, elsewhere hard frozen. COMMENT: Hazard of falling ice and rocks in areas exposed to the sun. GLENCOE AVALANCHE HAZARD 1500 HRS TUE 13/2/01 Dry conditions and colder temperatures have continued to re-freeze the old snow. The snowpack above 600 metres has a firm icy crust overlying wet snow which is generally stable. Slopes receiving morning sun develop a thin sun crust in the afternoon. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK WED 14/2/01 Settled conditions will continue but with freezing level forecast at 2700 metres. This will soften the surface layer of the snowpack and render cornices unstable. Although soft and moist the snowpack will further consolidate and remain generally stable. On steep scarp slopes wet snow will be moderately bonded and the avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Firm snow above 600m. ICING: Icy paths and rocks above 400m. COMMENT: Classic gullies such as Twisting, Forked etc. receiving ascents. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 13/2/01 The majority of the snowpack has a strong melt freeze-crust but the surface layers have begun to soften in the warmer temperatures. Deeper within the snowpack colder dry snow and some instability continues to exist. Moderately bonded areas are to be found in mainly sheltered locations above 900 metres on NE through to SE aspects. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK WED 14/2/01 The snowpack will be subject to severe thaw conditions at all levels causing stronger surface layers to soften and stability to become suspect. The snowpack will be moderately to weakly bonded with greatest hazard on steeper slopes above 800 metres on all aspects. The avalanche hazard will be Considerable (Category 3). Remaining cornices will be suspect. CLIMBING CONDITIONS SNOW DISTRIBUTION: Good cover from 750 metres. ICING: Subject to severe thaw conditions. COMMENT: Hazard of rock and ice fall during thaw. CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS TUE 13/2/01 It has been a dry and clear day with a strong South-West wind. Thaw-freeze cycle is continuing to improve general snowpack stability. However moderately bonded windslab still persists on North through East to South-West aspects above 850 metres: steep slopes and lee slopes below cornices are particularly affected. The avalanche hazard is Considerable (Category 3). Elsewhere the snowpack is well bonded and stable. Cornices are becoming increasingly unstable as temperatures rise throughout the day. AVALANCHE HAZARD OUTLOOK WED 14/2/01 A dry and very mild day is forecast, with freezing levels well above the summits and a strong South-West wind. Moderately bonded windslab will persist on North through East to South-West aspects above 850 metres. The avalanche hazard will remain Considerable (Category 3). Elsewhere the snowpack will be well bonded and stable. Increased risk of cornice collapse in mild conditions. CLIMBING CONDITIONS SNOW DISTRIBUTION: Depleted at lower levels, still good cover above 750 metres. ICING: Plenty ice remaining at higher levels, thaw-freeze cycle improving build up. COMMENT: Watch out for those cornices, some monsters remaining. -------------------------------------------------------------------------------
