Lo esencial
Recently formed storm slabs are sensitive to natural and human triggering. The Dec 4th weak layer will be one to watch for some time to come. Conservative route selection is in order.

Storm slabs sitting on top of the Dec 4th interface are found in the Alpine and at Treeline in lee and cross-loaded features. Recent field tests indicate that these slabs are sensitive to human triggering.

Weather Forecast
Thursday will be mainly cloudy with isolated flurries. Alpine temperatures should reach a high -6 °C. Ridge-top winds will be out of the south at 20-35 km/h. Friday and Saturday will bring a slight cooling trend.
Avalanche Summary
Several small loose dry avalanches were observed today mostly in steep Alpine terrain. Observation were somewhat limited due to limited visibility.
Snowpack Summary
12 to 15cm of new snow in the past 24hrs brings storm snow totals up to 35 to 45cm. The Dec 4th interface of surface hoar, sun crust and facets is very sensitive to snowpack stability tests indicating a high likelihood of human triggering. Storm slabs sitting on the Dec 4th interface are found in lee and cross-loaded terrain at Treeline and above.
