Avalanche Activity

LO for 8.1 Unstable windslab mainly on NE-E-S aspcts abve 900m. Deposits not expected to be extensive nor gain signif depth. Haz Low

Forecast Snow Stability: New unstable windslab will be deposited in wind sheltered areas, mainly on North-East through East to South aspects above 900 metres. Accumulations are not expected to be extensive nor gain significant depth. Steep coire rims, tops of gullies and flanks of ridges will be most affected. There will be a covering of soft snow on all aspects above around 300 metres. The avalanche hazard will be Low.

Snowpack Structure

Forecast Weather Influences: Winds are expected to be strong mainly West-North-Westerly overnight, easing during the morning to light to moderate mainly Westerly. Light snow showers at most levels are expected overnight, then a dry day. It will remain cold, with the freezing level around 200 or 300 metres.

ObservedSnowStability: There is a thin covering of new snow on all aspects above around 300 metres. Localised fresh unstable windslab has been deposited in wind sheltered areas, mainly on North-East through East to South aspects above 950 metres. Accumulations gaining depth are limited in extent, mainly on steep ground at the tops of gullies, around coire rims and along ridge flanks. The avalanche hazard is Low.
