Avalanche Problems

Storm Slabs

Avoid areas with overhead hazard.>Avoid cross loaded features.>

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3

Wind Slabs

Wind slabs are found in Alpine areas on lee and cross-loaded features. In most areas these slabs sit on a crust. Take the time to evaluate the bond of the wind slabs to the crusts below.
Be cautious as you transition into wind affected terrain.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 4

Loose Wet

Solar aspects are susceptible to increasing avalanche danger each day as solar radiation affect the snowpack. Plan your day to avoid exposure to large sunny slopes in the afternoons.
Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.>Make your travel plans to take advantage of overnight freezing.>

Aspects: North, North East, East.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
