Points saillants

Rugged travel persists at lower elevations, watch for early season hazards hidden just below the recent new snow. Field observations have been limited to date, evaluate the snowpack carefully before committing to big terrain. JH

Weather Forecast

An arctic ridge will remain in place over the region until at least the middle of the week.  Expect clearing skies and cooling temperatures (with overnight lows of -25 deg by Wednesday).

Snowpack Summary

Up to 20cm of new snow is covering a well settled early season snowpack (watch for buried windslab 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

Due to the number and quality of field observations
