Wind slab
- Above 800 m
Forecast Snow Stability: Instabilities in poorly bonded windslab will exist with further deposits becoming more widespread in the strong winds. Unstable accumulations in wind sheltered terrain mainly above 800 metres particularly in sheltered gullies and on steep slopes with a N, NE, E and SE aspect. Fragile cornices will exist above similar aspects. Cross loading may affect other wind sheltered locations. Wind exposed slopes will be firm and often icy with better stability. The avalanche hazard will be Considerable.
Forecast Weather Influences: Saturday night, the freezing level will briefly rise above the summits then rapidly fall to be around 500 metres for the rest of the period. Initially some overnight rain followed by snow showers through the day. The Southerly winds will reach storm force Saturday night before veering Westerly easing but remaining strong through the day. Observed Weather Influences: Overnight, the freezing level lowered to 350 metres and snow fell above 300 metres. Daybreak was a lovely clear morning but these conditions didn\'t last long clouds quickly covered the summits. The freezing level has slowly risen through the morning but midday summit temperatures were still around minus four degrees Celsius and the freezing level continues to slowly rise. Southerly winds were generally moderate in strength with snow showers falling mainly above 550 metres. ObservedSnowStability: Moderately bonded windslab exits in wind sheltered locations.. Greatest accumulations are in sheltered gullies, scarp slopes, coire rims and on steep slopes on North-West through North to Easterly aspect above 850 metres. Fragile cornices also exist above similar aspects. The avalanche hazard is Moderate.
