Problems

Loose Dry

Temperatures are warmer up high today due to an inversion. Caution on and under steep solar aspects when the sun is shining on them. Loose avalanches will most likely originate from cliffs.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood

Likely

Expected Size

1 - 2

Wind Slabs

Wind slabs at ridge crests and in the alpine from the strong winds during the last storm may still catch a rider off guard.

Use ridges or ribs to avoid pockets of wind loaded snow.Be cautious as you transition into wind affected terrain.

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

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3

Storm Slabs

Storm snow instabilities still exist in the recent storm snow. Although it appears to be bonding well, another day or two of settlement and observations is needed before it is no longer considered to be a problem.

The new snow will require several days to settle and stabilize.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3
