Some thin new wind slabs are expected to develop with the forecast new snow. New snow is not expected to bond well to the old hard surface where surface hoar and/or facets exist.
Confidence
Fair - Timing, track, or intensity of incoming weather system is uncertain
Weather Forecast
Overnight and Wednesday: Overcast with light Southwest winds and 3-5 cm of snow above about 700 metres elevation. Freezing level is expected to continue to lower during the day down to about 500 metres as light precipitation continues.Thursday: Continued light precipitation bringing 3-5 cm of snow to all elevations. Moderate Northwest winds becoming light Westerly.Friday: Gradual clearing during the day as the precipitation ends. Freezing level expected to remain at valley bottoms as cooler arctic air moves in from the North.
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.
