Poor - Due to the number of field observations

Synopsis: An arctic ridge of high pressure will persist over the BC Interior and Yukon for the next several days. Friday: Mainly sunny with extreme outflow winds in the valleys and moderate to strong northeasterly alpine winds. Treeline temperatures expected to be around -10. Saturday: Mainly sunny with some thin cloud possible, outflow winds easing moderate in valley bottoms and light to moderate northeasterly alpine winds. Treeline temperatures expected to be around -15 but not much colder in the alpine. Sunday: Increased cloud, windy, and cold with the possibility of above freezing temperatures between 1500m and 2000m.

Several wind slab avalanches up to Size 2 were observed just below ridge crests between 1500m and 1800m in the Ashman Ridge area last Sunday.

Recent storm snow is settling and gaining strength, however weaknesses at the old snow interface down approximately 40cm may still need time to heal. In the Ashman Ridge area on Sunday, this interface gave easy compression test results. Northerly outflow winds are likely forming fresh wind slabs in exposed lee terrain and scouring windward terrain. Average snowpack depths near treeline are highly variable, but around a metre in sheltered areas.
