Problems

Storm Slabs

An icon showing Storm Slabs

Storm slabs will build with the forecasted heavy snow. New snow may take some time to bond to the underlying crusts.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Likely - Very Likely

Expected Size

1 - 2.5

Loose Wet

An icon showing Loose Wet

The snowpack at lower elevations remains slurry and saturated. As the snowpack approaches its melting point it will result in a loss of cohesion.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood

Possible

Expected Size

1 - 1.5
