Confidence

Fair - Timing or intensity of solar radiation is uncertain on Tuesday

Weather Forecast

Overnight and Tuesday: Light Northwest winds increasing to moderate overnight. Freezing level at valley bottom overnight and rising to 800 metres during the day. Alpine temperatures -9.0 overnight, some chance of an inversion in the alpine during the day that may bring temperatures up to about -3.0.Wednesday: Winds are expected to switch to the West-Southwest and remain moderate. Mostly sunny skies with warm temperatures in the alpine (inversion continues).Thursday: Alpine temperatures should cool down to about -6.0 under mostly clear skies and moderate Southwest winds.

Avalanche Summary

Loose snow avalanches up to size 1.5 continue to be reported from steep terrain.

Snowpack Summary

New surface hoar continues to grow in areas that are sheltered from the wind. Recent light snowfalls have been transported into soft wind slabs in the alpine. Continued wind effect may stiffen these wind slabs and allow for longer fracture propagations. Deeper instabilities have been inactive, but may still be triggered by large loads in thin snowpack areas.

Avalanche Problems

Wind Slabs

The wind continues to transport light dry snow into soft wind slabs in the lee of terrain features at higher elevations. Stubborn wind slabs may be triggered by the additional load of a skier or rider.
Be cautious as you transition into wind affected terrain.>Use ridges or ribs to avoid pockets of wind loaded snow.>

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 4

Loose Dry

Loose dry snow is expected to continue to sluff out of steep terrain.
Avoid travelling on ledges and cliffs where sluffing may have severe consequences.>Be aware of party members below you that may be exposed to your sluffs.>

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2
