It may only be November but it's real out there. Touchy conditions, continued loading and short days make it a good time for conservative decisions as we all get our heads back into winter mode. This is only the beginning. Play safe. DM

Avalanche Problems

Storm Slabs

Up to a meter of storm snow and strong southerly winds have buried a touchy surface hoar layer. This layer is very reactive to skier traffic. Natural avalanches have been running long distances, reaching valley bottom and across skiers uptracks.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 2 - 3

Wind Slabs

Continued snowfall overnight under the influence of steady strong southerly winds at ridgetop are loading snow onto lee slopes. Expect wind slabs on northerly aspects treeline to alpine. Natural avalanches are possible and may step down deeper.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
