LOCHABER AVALANCHE HAZARD 1500 HRS WED 20/3/02 Localised shallow surface instabilities are present on many steep aspects. Below 1150m, this surface snow is wet and the surface instabilities extend to lower altitudes. Elsewhere the snowpack is generally stable. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 21/3/02 Some light snowfall is expected overnight and during Thursday with light winds. Snowpack stability will remain generally good. Localised surface instabilities will be present on many steep aspects, mainly above 1000m. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: General cover remains above 800m. Wet snow below 1100m. ICING: Freezing level expected to lower overnight. COMMENT: Many ice routes still receiving ascents. ------------------------------------------------------------------------------- CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS WED 20/3/02 The snowpack is generally well bonded and stable on all aspects. Winds have been light and variable with light snowfall above 800 metres. Most aspects have fresh snow cover and isolated moderately bonded windslab deposits are present but easily avoided above 900 metres. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 21/3/02 Light and occasional snow showers on a light North-East wind. Shallow isolated moderately bonded windslab deposits will form on South to West aspects above 900 metres. These deposits will affect only the deepest of hollows and will be easily avoided. The avalanche hazard will be Moderate (Category 2) CLIMBING CONDITIONS SNOW DISTRIBUTION: Fresh snow down to 700 metres. ICING: Very good where exposed, a lot still buried though. COMMENT: Main gullies complete, open faces stripped. ------------------------------------------------------------------------------- GLENCOE AVALANCHE HAZARD 1500 HRS WED 20/3/02 A light dusting of snow fell overnight above 650m, no significant build up or drifting was found during observations to day. The underlying older snowpack is generally firm above 700m with some softening occurring as the day progressed. Stability was found to be good on all but the steepest slopes and gullies where shallow wet snow instabilities remain. The avalanche hazard is Low (Category 1). Cornices remain prone to collapse. AVALANCHE HAZARD OUTLOOK THU 21/3/02 Precipitation will fall as light snow overnight becoming moderate rain or sleet at all levels as temperatures rise early Thursday morning. Wet snow instabilities will exist on the steepest of slopes mainly in sheltered gullies and on North-West to Easterly aspects. In these areas the avalanche hazard will be Moderate (Category 2). Cornices will remain prone to collapse and should be carefully considered when route planning; elsewhere the snowpack will become soft and moist but will generally be stable. CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow above 500m. ICING: Highest routes only COMMENT: Milder conditions for Thursday with freezing levels at 1100 metres. Highest routes offer best hope for climbing. Wet snow instabilities on route exits. ------------------------------------------------------------------------------- NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 20/3/02 It was a bright clear morning with cloud and very light snow moving in during the day. Winds for snow transport were insignificant. For a period of about one hour numerous loose snow avalanches occurred. These were on North and West aspect above 1000 metres. The avalanche hazard is Considerable (Category 3). AVALANCHE HAZARD OUTLOOK THU 21/3/02 Temperatures will remain well below freezing for the forecast period. Winds will be light from the North- East with some snow showers. The deeper snowpack has very good stability. The loose surface snow instability will persist. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Good plateau ski touring on all but some West aspects. ICING: Wet ice and rock in places but still reasonable for the area. COMMENT: In the current conditions, rapid temperature change and direct sun will produce loose snow avalanches. ------------------------------------------------------------------------------- SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 20/3/02 It has remained cool with some snow showers. The snowpack remains generally well bonded with isolated areas of unconsolidated snow on most aspects above 900 metres. These are generally shallow but where they are at their deepest and overlie snow-ice on steeper slopes the avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK THU 21/3/02 It will continue to be cold with some light snow showers overnight but then the freezing level will rise to around 900 metres early morning. Above this level there will be little change to the snowpack with the deepest new snow to be found on SW to NW aspects. On lower altitudes there will be consolidation in softer deposits. Where deeper deposits form over snow-ice on steeper ground above 900 metres the avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy below 900 metres. Deepest on N and E aspects. ICING: Has improved in the colder conditions. COMMENT: Freezing level will be around 900 metres. -------------------------------------------------------------------------------
