NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 11/2/98 Some rain and very mild temperatures are maintaining a steadily thawing, patchy snowpack. The largest accumulations of snow lie on E to SE aspects. Some collapse-prone cornices remain over these slopes and in these locations there is a Moderate (Category 2) hazard of avalanche. Stability is good in most other places. AVALANCHE HAZARD OUTLOOK THU 12/2/98 Forecasted very mild temperatures with some rain will sustain the current thaw. Cornices over steep E to SE aspects will continue to soften and become unstable, giving a Moderate (Category 2) hazard of avalanche on the scarp slopes below them. Further depletion of what remains of the snowpack can be expected over the period. CLIMBING CONDITIONS SNOW DISTRIBUTION: Patchy everywhere. Effective snow line approx. 1030m on N aspects and 900m on E to SE aspects (and rising by the hour!) ICING: Continues to decline in quantity and quality. Gullies still have some life in them for the time being. COMMENT: Much mildness and blackness, therefore not much whiteness. LOCHABER AVALANCHE HAZARD 1500 HRS WED 11/2/98 Heavy thawing and rain to above the summits, have depleted the snowpack. Remaining snow is mainly in N and E facing gullies above 1000m. The snowpack is generally stable at all levels. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK THU 12/2/98 Very mild conditions and continuing high amounts of rain, will prevail throughout Thursday. This will continue to thaw the snowpack at all levels, some wet snow instabilities will be present on steep NE and E facing slopes. The avalanche hazard will be Moderate (Category 2). There will be a hazard of full depth wet snow avalanches where the underlying ground surface is particularly smooth e.g. the rock slabs in Coire an Lochain of Aonach Mor. Cornices will also continue to slump and may collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Main accumulations remain in N and E facing corries above 1000m. ICING: Freezing level remaining well above the summits. COMMENT: Climbing conditions likely to deteriorate in the thaw. Hazard of falling rock and ice. GLENCOE AVALANCHE HAZARD 1500 HRS WED 11/2/98 Heavy thaw conditions with rain at all levels have reduced and stabilised the snowpack. Greatest remaining deposits of snow are to be found in the high NE facing corries and sheltered summit gullies. The avalanche hazard has become Low ( Category 1 ) . Remaining cornices are unstable . AVALANCHE HAZARD OUTLOOK THU 12/2/98 Mild, wet and windy conditions will continue overnight and on Thursday, maintaining the snowpack in a soft, moist and stable condition. The avalanche hazard will be Low ( Category 1 ) and remaining cornices will be prone to collapse. CLIMBING CONDITIONS SNOW DISTRIBUTION: Wet snow above 800m. ICING: Thawing ice above 900m. COMMENT: Caution required on ridges in strong winds. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS WED 11/02/98 The steady thaw conditions have left the sparse snowpack very wet but generally stable. Remaining cornices are overhanging, wet and unstable. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK THU 12/02/98. Very mild conditions with light rain and storm force winds will leave the sparse snowpack very wet at all levels. Any remaining cornices, mostly on N to E facing slopes will be prone to collapse. The avalanche hazard will be Low (Category 1). CLIMBING CONDITIONS SNOW DISTRIBUTION: There is still a bit on N to E facing corries and sheltered areas. Thawing at all levels. ICING: Virtually non-existent! Rock and ice fall are hazards during thaw. COMMENT: ...El Nino strikes again...! CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS WED 11/2/98 Heavy rain at all levels, with temperatures of plus 6 at the summits, has saturated the snowpack. The snow has become moderately bonded at the tops of steep gullies and hollows above 950m. In these localised areas the avalanche hazard is Moderate (Category 2). Elsewhere the snowpack is well bonded and stable. AVALANCHE HAZARD OUTLOOK THU 12/2/98 The snowpack will remain saturated as heavy rain and mild temperatures continue overnight. This will cause the moderate bonding of the snowpack on steep slopes at the tops of gullies and hollows above 950m to persist. The avalanche hazard will be Moderate (Category 2). Any existing cornices will be prone to sudden collapse. In most areas the snowpack will be well bonded and stable. CLIMBING CONDITIONS SNOW DISTRIBUTION: Coire Ardair continues to retain the most snow, very patchy elsewhere. ICING: Starting to melt in the continuing thaw. COMMENT: Danger from falling ice and rocks in Coire Ardair. -------------------------------------------------------------------------------
