NORTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 10/2/98 Recent thaw conditions have resulted in a much depleted and generally moist but stable snowpack. Colder conditions overnight have re-frozen surface layers at higher elevations above 1000m. Avalanche hazard Low (Category 1). AVALANCHE HAZARD OUTLOOK WED 11/2/98 A return to milder temperatures with heavy rain and hurricane force SW winds on the summits will result in any remaining cornices becoming heavy and prone to collapse. Moderate (Category 2) hazard of avalanche on scarp slopes immediately below these cornice lines, primarily above steep E to SE aspects. CLIMBING CONDITIONS SNOW DISTRIBUTION: Only patches remaining ICING: Hanging in there! Many gullies becoming broken. Thaw likely to depredate what little remains. COMMENT: Not good! LOCHABER AVALANCHE HAZARD 1500 HRS TUE 10/2/98 Some accumulations of fresh snow exist at the tops of NE aspects above 1100m. This new snow is moderately well bonded to the underlying old snow. In these locations the avalanche hazard is Moderate (Category 2). Elsewhere the snowpack is stable. AVALANCHE HAZARD OUTLOOK WED 11/2/98 Heavy rain to above the summits is expected overnight and during Wednesday. The snowpack will thaw and start to consolidate at all levels. Stability will generally be good. The avalanche hazard will be Low (Category 1). 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. GLENCOE AVALANCHE HAZARD 1500 HRS TUE 10/2/98 The snowpack is consolidating and stabilising. Remaining cornices are unstable. Where soft wet slab is lying on steep corrie headwalls and summit gullies the avalanche hazard is Moderate (Category 2) AVALANCHE HAZARD OUTLOOK WED 11/2/98 Mild conditions will bring heavy rain to well above the summits. Cornices found above N to E facing slopes will be very unstable. The snowpack will become saturated. In summit gullies and corrie headwalls which contain soft wet slab the avalanche hazard will be Considerable (Category 3). CLIMBING CONDITIONS SNOW DISTRIBUTION: Wet snow above 800m. ICING: Thawing ice above 900m. COMMENT: Climbing conditions poor. Caution required on ridges in strong winds. SOUTHERN CAIRNGORMS AVALANCHE HAZARD 1500 HRS TUE 10/2/98 A slight freeze above 950m overnight followed by thaw conditions has left the snowpack stable. Remaining cornices have firmed up but are still overhanging and unstable. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK WED 11/2/98 Very mild conditions with heavy 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 and may cause wet snow avalanches below them. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: There is still a bit on N to E facing corries and sheltered areas. Thawing at all levels. ICING: Lean! Rock and ice fall are hazards during thaw. COMMENT: How do you spell Armageddon...? CREAG MEAGAIDH AVALANCHE HAZARD 1500 HRS TUE 10/2/98 A mere trace of snow on the summit areas with a much lowered freezing level has led to the general stabilisation of the snowpack. The avalanche hazard is Low (Category 1). AVALANCHE HAZARD OUTLOOK WED 11/2/98 Heavy rain at all levels with the freezing level rising to well above the summits will again saturate the snowpack. Most slopes will remain generally well bonded, but very steep slopes may become only moderately well bonded. Cornices where they exist may be prone to sudden collapse. The avalanche hazard will be Moderate (Category 2). CLIMBING CONDITIONS SNOW DISTRIBUTION: Becoming increasingly patchy. ICING: Stabilised a bit today (10/2/98) but is expected to virtually disappear in the next few days. COMMENT: It now looks as if this thaw will last a considerable time. Not good!! -------------------------------------------------------------------------------
