The Winter Permit System is not yet in effect. Expect sporty early season conditions with thinly buried hazards at lower elevations, open creeks and lots of alder. Dry powder can be found on sheltered slopes about 1800m.

Summary

Weather Forecast

Unsettled weather with cool temperatures, flurries, and moderate westerly winds at ridgetop are forecasted. Freezing levels are expected to stay below 1300m.

Snowpack Summary

Above 1800m 40cm of snow overlies a series of crusts. Stability tests find moderate resistant planar shears above the Nov 6 crust. Moderate to strong winds from the SW and the NE transported snow and formed isolated windslabs in the alpine.

Avalanche Summary

Recent avalanche activity has been limited to sluffing off of steep slopes.

Confidence

Due to the number of field observations

Problems

Wind Slabs

40cm of storm snow overlies a crust. Strong south winds early last week created windslabs on exposed lee slopes. Winds shifted to northerly, reverse loading many slopes. Watch for pockets of windslab in the alpine on exposed slopes.

Be cautious as you transition into wind affected terrain.Make observations and assess conditions continually as you travel.
