Problems

Wind Slabs

An icon showing Wind Slabs

Recently formed wind slabs can be found in lee features near ridge crests, and in cross-loaded gullies.

  • Be careful with wind loaded pockets, especially in steep confined alpine terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 2

Loose Dry

An icon showing Loose Dry

Enough new snow has fallen over the past few days to produce Loose Dry avalanches in steep terrain. Use caution in exposed or confined features where small avalanches can have high consequences.

Aspects: All aspects.

Elevations: Alpine.

Expected Size

1 - 1
