Weather Forecast

Weather for Thursday:Mainly cloudy with isolated flurries.Precipitation: Trace.Alpine temperature: High -4 °C.Ridge wind southwest: 40-55 km/h.Freezing level: 1800 metres.

Avalanche Summary

No new avalanches were observed on Wednesday but observations were limited.

Snowpack Summary

The warm temperatures are helping the upper snowpack to settle and producing moist snow on steeper solar aspects. At tree line 50-60cm of settled snow is overlying a facet layer that is about 70cm down producing hard test results. The bottom quarter of the snowpack is weak and consists of facets, depth hoar and the early season crusts. Expect continued wind transport for Wednesday especially on lee features and cross loaded gullies.
