Watch for early season hazards like stumps and rocks lurking below the surface. There have been limited field observations to date, evaluate the snowpack carefully before committing to any exposed terrain. JH

Weather Forecast

A mix of sun and cloud and a few flurries Friday into Saturday will give way to snowfall by Sunday afternoon as a Low pressure system makes it's way inland. Total accumulations of 10-20cm are expected by Monday morning.

Snowpack Summary

Near the divide, the snowpack above 2000m is over 100cm deep, but tapers quickly below. The early season snowpack is generally well consolidated. Pockets of windslab likely exist in exposed lees. A mid November crust persists down 30-80cm, it was well bonded in areas observed today but warrants evaluation for the foreseeable future.

Avalanche Summary

No recent activity observed.

Confidence

Due to the number and quality of field observations
