Stephen Holeczi,
Some new snow should refresh the skiing. If this snow is overlying a harder surface it may run further than anticipated if initiated.
Summary
Weather Forecast
A decent freeze on Thursday AM with afternoon freezing levels to 1800-1900m. There should be more solar input, especially along the foothills. Winds will remain light through the day and into Friday.
Snowpack Summary
5-25cm over the last 24 hours has created storm slabs. These overly crusts that exist on all aspects below 2300m and high into the alpine on solar aspects. High N aspects still hold dry powder and some wind effect on lee slopes. Crusts are breaking down and reforming almost daily depending on solar input and freezing levels.
Avalanche Summary
Sunshine ski area was reporting soft storm slabs and loose dry avalanches on most aspects up to size 1.5 with ski cuts and explosives. They were running far on the crusts and harder surfaces below.
Confidence
Problems
Loose Wet

Aspects: All aspects.
Elevations: Treeline, Below Treeline.
