40cm of storm snow has fallen since Saturday. West and NW winds have moved this snow onto lee aspects. South facing aspects are particularly likely trigger areas where the bonding of the new snow to the old melt freeze crust is weakest.
Weather Forecast
Day time temperatures will progressively rise to the mid-twenties by Sunday. Overnight temperatures will break the freezing mark by Saturday. Winds will ease and the sun will shine. Finally!!
Snowpack Summary
40cm of snow has fallen in the Icefields area since Saturday. This has formed pockets of windslab at and above treeline. Bonding of this slab on Southerly slopes should be considered suspect. Below the new snow a thick melt freeze crust layers cap isothermal snow below. Sun crusts extend high into the alpine on South facing slopes.
Avalanche Summary
No reports of avalanches today.
Confidence
The weather pattern is stable on Thursday
