Avalanche Problems

Storm Slabs

Significant snow accumulations are expected over the next 24 hrs. How this snow bonds to the widespread melt freeze crust formed on April 12 is the big question. Be sure evaluate the storm snow interface before committing to big slopes.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

These deeper layers can wake up unexpectedly. The forecasted storm snow may overload deep layer in some locations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4

Loose Wet

With cooling temperatures this problem will likely ease for the next few days. Remember that the sun is intense this time of year and can create isothermal conditions in short order. Rain at low elevations can also bring this problem to life.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
