Forecast Snow Stability: Existing windslab instabilities will consolidate in most places, before new areas of moderately bonded windslab again form in wind sheltered locations. Sheltered locations such as gullies, scarp slopes and steep coire rims and on slopes with a North through East to South-Easterly aspect above 850 metres will be mostly affected. Cornices will be unstable above similar aspects. The avalanche hazard will be Moderate.
Forecast Weather Influences: The freezing level will briefly rise above the summits in the early hours of Tuesday morning with rain. Then, freezing level will fall to around 600 metres with snow showers and strong to gale force Westerly winds. Observed Weather Influences: The freezing level rose to around 900 metres by 09.45hrs this morning then it slowly fell to around 800 metres. Intermittent precipitation fell mostly as snow above 850 metres and the winds were fresh to strong from a North-Westerly direction. Brighter, drier and lesser winds in the afternoon.
ObservedSnowStability: The older moist snowpack has generally consolidated. New accumulations of moderately bonded windslab was developing in wind sheltered locations. Areas mostly affected are sheltered gully exits, coire headwalls and steep slopes on North-East to South-Easterly aspects above 950 metres. The avalanche hazard is Moderate.
