In sintesi

Watch for early season hazards just below the snow surface, with ongoing cold temperatures even a minor injury could result in serious consequences.

Weather Forecast

The arctic ridge persists through Thursday, giving clear skies, calm winds and cold temps (Lows of -30, Highs of -25). On Friday a low pressure system moving inland from the coast will give flurries and snow showers through Saturday (total accumulations of 5-10 cm). Temperatures remain cold with overnight lows of -24 and daytime highs of -20.

Snowpack Summary

Up to 20cm of low density snow is covering a well settled early season snowpack (watch for buried windslabs near ridges). The snowpack above 2000m is over 100cm deep near in the divide, but much shallower at lower elevations and in Eastern areas. A mid November crust down 40-90cm was well bonded in areas observed to date but warrants evaluation.

Avalanche Summary

No recent activity observed.

Confidence
