Confidence

Fair - Intensity of incoming weather systems is uncertain

Weather Forecast

Overnight and Thursday: Snow is forecast overnight and Thursday as the Arctic front moves south and cools the moist air left behind as the low pressure moves to the Southeast. Expect 3-5 cm in the North and 5-10 cm in the South. Light to moderate Northwest winds and freezing levels dropping down to about 500 metres by morning.Friday: Mix of sun and cloud as the cold arctic air dries out the airmass. Freezing levels at valley bottoms and moderate Northwest winds. Alpine temperatures around -12 C.Saturday: Mostly sunny with alpine temperatures around -10 C and light Westerly winds.

Avalanche Summary

No new avalanches reported.

Snowpack Summary

A solid melt-freeze crust has developed at all elevations on most aspects. New snow may bury surface hoar that has grown at and below treeline over the past few days. In the alpine new snow may not bond to the old surface depending on the timing of the cooling. Deeply buried weak layers continue to exist, however the bridging effect of the re-frozen upper snowpack may reduce the likelihood of triggering.

Avalanche Problems

Wind Slabs

Thin new wind slabs may develop above hard melt-freeze crusts. Surface hoar and/or facets on the crust may make an easy sliding layer.
Avoid freshly wind loaded features.>

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 2
