Avalanche Problems

Wind Slabs

Wind slabs up to 40 cm thick are reactive where they sit over sun crusts, or on temperature crusts on shady asp. Today at 1145 am there was a skier triggered size 2.5 avalanche from 60 m away on a SE asp (2700 m) of a sub-pk of Jimmy Simpson.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

Watch out for thin & steep areas and large loads such as cornice failure which could trigger deep weaknesses. Thin areas are veiled by the new snow. Pay attention to snow distribution and depth as you travel.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3

Loose Wet

Skies should clear tonight, and we should see another strong freeze. Expect increasing cloud tomorrow afternoon with the passage of a front. Cloud cover may vary through the region, so pay attention to solar affect triggering slides, and start early.

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

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
