The freezing level lowered fairly rapidly last night resulting in snowfall to glen level. In the mountains, the new snow is cold and dry, drifting readily in the fresh to strong winds. Small cornices have formed and unstable accumulations have developed in the most wind sheltered locations – such as gully tops and the last few metres around steep corrie rims or in steep burn lines. Whilst the distribution of these deposits is not widespread, they are locally significant and are capable of producing small avalanches which could easily dislodge anyone triggering the slope. Run outs are particularly bouldery at present. Â Given the continuing cold temperatures, consolidation is occurring at a slow rate. Exposed locations are scoured and icy.
Drifting still occurring above 800 metres even though it has stopped snowing. Cold, dry deposits really available for redistribution.
Deeper snow in the most wind sheltered locations. Gully tops and the last 10 to 15 metres around corrie rims.
Artificial accumulation here – snow fences doing their job. Steep corrie rims have the same effect. Small cornices have formed.
Exposed location at 900 metres; wind scoured and icy in places.
Better visibility today. A thin covering of fresh snow to glen level.
