NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SUN 26/1/03 This was a warm winter day with a Westerly wind. The snowpack, where sampled on the Great Slab in Coire an Lochain, is isothermal and two metres deep. It is moist and well bonded but punctuated by slush and ice layers. The avalanche hazard is Moderate (Category 2). AVALANCHE HAZARD OUTLOOK MON 27/1/03 The temperatures are finally expected to drop during the afternoon, heralding snow showers. The wind will continue to blow from the West creating some new load on Easterly aspects above 1000m. Near surface snow stability will not change significantly. Rockfall and cornice breaks will be a concern. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Snow has accumulated on the top of the Twin Burns and West Wall; otherwise a net loss everywhere. ICING: Considerable water flow being blown uphill in The Vent. COMMENT: This appears to be the end of the third winter-spring cycle this season. LOCHABER AVALANCHE HAZARD 1500 HRS SUN 26/1/03 A major thaw has taken place overnight and during Sunday with summit temperatures of around 5 degrees C. The snowpack is greatly reduced with wet snow deposits restricted to high gully lines and corries. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 27/1/03 A change to the current mild conditions will occur as snow and strong W winds move into the forecast area as Monday progresses. New snow accumulations will at first be limited to the tops of gullies and slopes were existing older deposits remain with a NE to E through to SE aspect. As Monday progresses fresh areas of snow will start to form at lower elevations in sheltered locations. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Thin and patchy. ICING: Becoming colder later on Monday. COMMENT: Looking better for the week ahead, could this be the start of winter, again? GLENCOE AVALANCHE HAZARD 1500 HRS SUN 26/1/03 Recent thaw conditions with very heavy rain at all levels have reduced the snow cover to patches in the higher gullies and corries. The remaining snowpack is generally stable. Avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 27/1/03 Mild conditions with rain at all levels will continue to affect the area overnight and through much of Monday. The remaining snowpack will be patchy and will mainly be found in the higher summit gullies and North to East facing corries. General snowpack stability will be good. The avalanche hazard will be Low (Category 1) but any remaining cornices will be prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy cover in high gullies and corries ICING: None at present COMMENT: Mild and wet for most of Monday getting colder with significant snowfall expected through the rest of the week. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS SUN 26/1/03 Overnight rain and very warm temperatures have devastated the remaining patchy snow cover. With temperatures of 9 degrees centigrade at 900 metres today the snowpack is soft, wet and generally stable on all aspects. Cover is restricted to limited patches above 950 metres. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 27/1/03 It will remain extremely warm overnight before temperatures start to lower on Monday morning. The patchy snow cover that exists above 950 metres will remain soft but generally stable on all aspects. By late afternoon it will have become cold enough for isolated wintry showers to occur. The avalanche hazard will be Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: Isolated patchy cover above 950 metres. ICING: Forget it! Plus 6.9 degrees at 1200 metres! COMMENT: Getting colder for the rest of the week... CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS SUN 26/1/03 It has become very mild with rain showers driven on a storm force South-South-West wind. This has had the effect of almost completely depleting what little snow cover we had. Only the very tops of the biggest North to East facing gullies above 900 metres hold any accumulations and these consist of well-bonded but soft wet snow. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK MON 27/1/03 It will remain very mild overnight with the freezing level well above the summits. During the day it will eventually become a little colder with wet snow over the summits. Snow deposits that survive in the bigger gullies on North to East aspects above 900 metres will consolidate further with fresh wet snow being driven into the same gullies on a gale force Westerly wind. These fresh deposits will make little difference to the current sparse conditions. The avalanche hazard will remain Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: It took me a while to find it! North to East facing gullies above 900 metres only. ICING: There isn't any! COMMENT: Hopefully getting a bit colder as I'm getting fed up with driving rain and gales! -------------------------------------------------------------------------------
