A strong arctic ridge remains over the interior creating outflow conditions along the coast. Clear and cold conditions persist. Thursday: Clear and sunny, treeline temperatures around -20C, mountaintop winds 40km/h SE in the morning decreasing during the dayFriday/Saturday: Clear and sunny, treeline temperatures around -20C, mountaintop winds light-to-moderate variable

On Tuesday, 2 size 1 avalanches were reported in the north of the region.  The first was a natural wind slab on a steep NW aspect. The second was a small skier triggered slab on a steep moraine feature with faceted snow.

Thin windslabs may still exist in isolated leeward features on a variety of aspects at treeline and in the alpine while wind-exposed features have become heavily scoured. Recent cold temperatures and clear skies are causing faceting of the upper snowpack which should be causing the remaining wind slabs to break-down. In more sheltered areas, several centimetres of dry snow may overlie a melt-freeze crust, surface hoar, facets, or a combination of the above. The mid and lower snowpack are generally well consolidated and there are currently no layers of concern. However, weak basal facets may still be a concern in isolated areas, especially thin snowpack areas at higher elevations.
